Terumi Inagaki; Asuka Sakamoto; Takumi Iwata; Yanrong Li, In recent years, the gap of energy demand among seasons or between daytime and nighttime in Japan are steadily expanding, and technological development concerning effective use of energy is an urgent issue coupled with recent environmental problems. We focus on fatty acids (capric acid, lauric acid and myristic acid) and their mixture having unique phase change characteristics as a working fluid for a heat exchange system with multistage latent heat storage. These fatty acids as heat storage materials are easy to handle and less influenced on human body near ambient conditions. When the fatty acids mixed with a suitable mixing ratio are in the liquid phase state, the thermophysical properties (density, viscosity, melting and freezing points, supercooling character, effects of mixing ratio and so on) were identified in order to establish a new heat exchange system with multistage latent heat storage. As a result, thermophysical properties of the fatty acids and their mixture were evaluated quantitatively and were newly proposed as an appropriate heat transfer database., Society of Chemical Engineers, Japan

Heat transfer by natural convection was also investigated in a horizontal enclosed rectangular container whose bottom plate was heated uniformly in both non-magnetic and vertical magnetic fields in order to estimate the heat transfer characteristics.

李艶栄; 染矢聡; 岡本孝司; 稲垣照美,Flow-induced acoustic resonance in a piping system containing closed coaxial side-branches was investigated experimentally. Resonance characteristics of the piping system were examined by a microphone. The results revealed that the resonance frequencies of the shear layer instability were locked in corresponding to the natural frequencies of the side-branches. Phase-averaged velocity fields were obtained two-dimensionally in the junction of coaxial side-branches by dynamic particle image velocimetry (PIV), while the acoustic resonance was induced at the first and second hydrodynamic modes. The DPIV can acquire time-series velocity fluctuations, then, two-dimensional phase delay maps under resonance and off-resonance conditions in the junction of coaxial side-branches were obtained. Experimental results show that the proposed phase delay map method costs less experiment and computation time and achieves a better accuracy and repetition than the phase-locking technique. In addition, the phase delay map method can obtain phase difference under the different frequency components.

化学工学論文集, 2016, [Reviewed] - Study on performance improvement of an axial flow hydraulic turbine with a collection device
Yasuyuki Nishi; Terumi Inagaki; Yanrong Li; Sou Hirama; Norio Kikuchi, The portable hydraulic turbine we previously developed for open channels comprises an axial flow runner with an appended collection device and a diffuser section. The output power of this hydraulic turbine was improved by catching and accelerating an open-channel water flow using the kinetic energy of the water. This study aimed to further improve the performance of the hydraulic turbine. Using numerical analysis, we examined the performances and flow fields of a single runner and a composite body consisting of the runner and collection device by varying the airfoil and number of blades. Consequently, the maximum values of input power coefficient of the Runner D composite body with two blades (which adopts the MEL031 airfoil and alters the blade angle) are equivalent to those of the composite body with two blades (MEL021 airfoil). We found that the Runner D composite body has the highest turbine efficiency and thus the largest power coefficient. Furthermore, the performance of the Runner D composite body calculated from the numerical analysis was verified experimentally in an open-channel water flow test., Turbomachinery Society of Japan

Journal of Flow Visualization and Image Processing, 2016, [Reviewed] - Unsteady Flow Analysis of an Axial Flow Hydraulic Turbine with Collection Devices Comprising a Different Number of Blades
Yasuyuki Nishi; Terumi Inagaki; Yanrong Li; Sou Hirama; Norio Kikuchi, We previously devised a new type of portable hydraulic turbine that uses the kinetic energy of an open-channel flow to improve output power by catching and accelerating the flow. The turbine contains an axial flow runner with an appended collection device and a diffuser section that is not axisymmetric. The objective of this study is to determine how interference between the collection device and the runner influences performance characteristics of the turbine. We investigated the performance characteristics of the turbine and flow field for different numbers of blades during both unsteady and steady flow. During an unsteady flow, the maximum values of power coefficients for three and two blades increased by approximately 8.8% and 21.4%, respectively, compared to those during a steady flow. For the three-blade runner, the power coefficient showed small fluctuations, but for the two-blade runner, the power coefficient showed large fluctuations. These fluctuations in the power coefficient are attributed to fluctuations in the loading coefficient, which were generated by interference between the runner and the diffuser section of the collection device., SCIENCE PRESS

Yanrong LI; Satoshi SOMEYA; Koji OKAMOTO; Terumi INAGAKI;; Yasuyuki NISHI, Flow-induced acoustic resonance in a piping system containing closed tandem side branches was investigated experimentally. Velocity perturbation was induced at the mouth of a cavity by using two pumps and a block. An unusual acoustic mode change from a higher to a lower mode was observed when the flow rate in the main pipe increased. This phenomenon was examined by high time-resolved particle image velocimetry (PIV). It was found that fluid flows at different points in the cavity have some phase differences between them and that they interact with each other. The relationship between the fluid flows was clarified and the phase difference between the acoustic pressure fluctuations at different points in the cavity was obtained. Using these data, the phase delays of oscillations at different points were two-dimensionally mapped. This two-dimensional phase map was helpful in clarifying the feedback mechanism of self-induced vibrations.

Water was chosen as the working fluid in order to achieve high Rayleigh number [low. The velocity field and temperature field in the container were experimentally visualized and analyzed by PIN and LIE, respectively, in order to examine the relationship between heat transfer and fluid flow Numerical simulation was conducted with [ES in order to validate the experimental results. The heat transfer coefficient obtained from the experimental results was found to be consistent with the heat transfer correlations proposed previously. Heat transfer coefficient and fluid flow obtained from the numerical simulation were found to coincide well with the experimental results., SOC CHEMICAL ENG JAPAN
KAGAKU KOGAKU RONBUNSHU, 2015, [Reviewed] - Study on an Undershot Cross-Flow Water Turbine with Straight Blades
Yasuyuki Nishi; Terumi Inagaki; Yanrong Li; Kentaro Hatano, Small-scale hydroelectric power generation has recently attracted considerable attention. The authors previously proposed an undershot cross-flow water turbine with a very low head suitable for application to open channels. The water turbine was of a cross-flow type and could be used in open channels with the undershot method, remarkably simplifying its design by eliminating guide vanes and the casing. The water turbine was fitted with curved blades (such as the runners of a typical cross-flow water turbine) installed in tube channels. However, there was ambiguity as to how the blades' shape influenced the turbine's performance and flow field. To resolve this issue, the present study applies straight blades to an undershot cross-flow water turbine and examines the performance and flow field via experiments and numerical analyses. Results reveal that the output power and the turbine efficiency of the Straight Blades runner were greater than those of the Curved Blades runner regardless of the rotational speed. Compared with the Curved Blades runner, the output power and the turbine efficiency of the Straight Blades runner were improved by about 31.7% and about 67.1%, respectively., Hindawi Limited

化学工学論文集, 2015 - Carbon-nanotube nanofluid thermophysical properties and heat transfer by natural convection
Yanrong Li; Shintarou Suzuki; Terumi Inagaki and Noriko Yamauchi, We measured the thermophysical properties of suspensions of carbon nanotubes in water as a type of nanofluid, and experimentally investigated their heat transfer characteristics in a horizontal, closed rectangular vessel. Using a previously constructed system for high-reliability measurement, we quantitatively determined their thermophysical properties and the temperature dependence of these properties. We also investigated the as yet unexplained mechanism of heat transport in carbon-nanotube nanofluids and their flow properties from a thermal perspective. The results indicated that these nanofluids are non-Newtonian fluids, whose high viscosity impedes convection and leads to a low heat transfer coefficient under natural convection, despite their high thermal conductivity., IOP PUBLISHING LTD
Proceedings of Power MEMS 2014, Nov. 2014 - The Flow Field of Undershot Cross-Flow Water Turbines Based on PIV Measurements and Numerical Analysis
Yasuyuki Nishi; Terumi Inagaki; Yanrong Li; Ryota Omiya and Kentaro Hatano, The ultimate objective of this study is to develop a water turbine appropriate for low-head open channels to effectively utilize the unused hydropower energy of rivers and agricultural waterways. The application of a cross-flow runner to open channels as an undershot water turbine has been considered and, to this end, a significant simplification was attained by removing the turbine casing. However, the flow field of an undershot cross-flow water turbine possesses free surfaces, and, as a result, the water depth around the runner changes with variation in the rotational speed such that the flow field itself is significantly altered. Thus, clear understanding of the flow fields observed with free surfaces to improve the performance of this turbine is necessary. In this study, the performance of this turbine and the flow field were evaluated through experiments and numerical analysis. The particle image velocimetry technique was used for flow measurements. The experimental results reflecting the performance of this turbine and the flow field were consistent with numerical analysis. In addition, the flow fields at the inlet and outlet regions at the first and second stages of this water turbine were clarified., Turbomachinery Society of Japan

Terumi Inagaki; Toshihiro Isshiki; Yanrong Li, This study aims to elucidate the phenomena of the coagulation and cooling process of the phase-change thermal storage medium sodium acetate trihydrate. The three-dimensional coagulation and cooling process of pure sodium acetate trihydrate without additives during thermal storage in the liquid phase were visualized using an infrared camera and a video camera in a horizontal enclosed rectangular container and a horizontal rectangular container with a free surface. Image processing based on the acquired visualization data was carried out with a computer, and various physical quantities peculiar to the cooling process were elucidated experimentally. As a result, we clarified for the first time the relation between the degree of critical supercooling and the average cooling velocity. Moreover, the influence of the degree of critical supercooling on the coagulation process was clarified three-dimensionally and phenomenologically using a series of visual and thermal images., SOC CHEMICAL ENG JAPAN

Journal of Fluid Science and Technology, Jul. 2014 - Study on an Undershot Cross-Flow Water Turbine
Yasuyuki Nishi; Terumi Inagaki; Yanrong Li; Ryota Omiya and Junichiro Fukutomi, This study aims to develop a water turbine suitable for ultra-low heads in open channels, with the end goal being the effective utilization of unutilized hydroelectric energy in agricultural water channels. We performed tests by applying a cross-flow runner to an open channel as an undershot water turbine while attempting to simplify the structure and eliminate the casing. We experimentally investigated the flow fields and performance of water turbines in states where the flow rate was constant for the undershot cross-flow water turbine mentioned above. In addition, we compared existing undershot water turbines with our undershot cross-flow water turbine after attaching a bottom plate to the runner. From the results, we were able to clarify the following. Although the effective head for cross-flow runners with no bottom plate was lower than those found in existing runners equipped with a bottom plate, the power output is greater in the high rotational speed range because of the high turbine efficiency. Also, the runner with no bottom plate differed from runners that had a bottom plate in that no water was being wound up by the blades or retained between the blades, and the former received twice the flow due to the flow-through effect. As a result, the turbine efficiency was greater for runners with no bottom plate in the full rotational speed range compared with that found in runners that had a bottom plate., SCIENCE PRESS

Proceedings of the 16th International Symposium on Flow Visualization, Jun. 2014, [Reviewed] - Study on the Flow Field of an Undershot Cross-flow Water Turbine
Yanrong Li; Yasuyuki Nishi; Terumi Inagaki; Kentarou Hatano, The purpose of this investigation is to research and develop a new type water turbine, which is appropriate for low-head open channel, in order to effectively utilize the unexploited hydropower energy of small river or agricultural waterway. The application of placing cross-flow runner into open channel as an undershot water turbine has been under consideration. As a result, a significant simplification was realized by removing the casings. However, flow field in the undershot cross-flow water turbine are complex movements with free surface. This means that the water depth around the runner changes with the variation in the rotation speed, and the flow field itself is complex and changing with time. Thus it is necessary to make clear the flow field around the water turbine with free surface, in order to improve the performance of this type turbine. In this research, the performance of the developed water turbine was determined and the flow field was visualized using particle image velocimetry (PIV) technique. The experimental results show that, the water depth between the outer and inner circumferences of the runner decreases as the rotation speed increases. In addition, the fixed-point velocities with different angles at the inlet and outlet regions of the first and second stages were extracted., TRANS TECH PUBLICATIONS LTD

Proceedings of the 9th International Student Conference at Ibaraki University, Nov. 2013, [Reviewed] - Characterization of periodic flow structure in a small-scale feedback fluidic oscillator under low-Reynolds-number water flow
Yanrong Li; Satoshi Someya; Toru Koso; Shinichiro Aramaki; Koji Okamoto, Numerical simulation and experimentation using high time-resolved particle imaging velocimetry were conducted in order to clarify the flow characteristics in a small-scale feedback fluidic oscillator operated under low-Reynolds-number water flow. Flow oscillations were triggered by the Coanda effect and a periodically oscillating jet. Based on spectral analysis of the velocity fluctuations inside the oscillator body, the Strouhal number was not constant and the frequency was not linear with respect to the flow rate for the Reynolds number range from 238 to 714. The flow rate fluctuations of the feedback flows through the two feedback channels were determined quantitatively. By comparing the simulation and experimental results, the mechanism of the small-scale feedback fluidic oscillator was clarified by considering the time for a jet to oscillate from the center of the control region to either of the attachment walls and the time for a jet to oscillate from either of the attachment walls to the center of the control region separately.

JOURNAL OF VISUALIZATION, Aug. 2011 - Lifetime-based phosphor thermometry of an optical engine using a high-speed CMOS camera
Satoshi Someya; Mitsunori Uchida; Kaoru Tominaga; Hayato Terunuma; Yanrong Li; Koji Okamoto, The surface temperature inside an optical engine was measured both with and without heating the intake gas. The temperature distribution was measured by lifetime-based phosphor thermometry using 10 time-sequential images during a single decay recorded by a non-intensified high-speed complementary metal oxide semiconductor camera and by accounting for the pixel-to-pixel variation in the nonlinearity of the sensor. Consequently, the system was simple and compact. One goal of this research is to use a single camera to measure the temperature field because it is easy to use such a system in practical experiments. The shot-to-shot standard deviation of the decay constant for uniform temperature conditions was 0.17-0.33% at 80-160 degrees C and it varied +/- 0.15% with position, indicating that the pixel nonlinearity is highly nonuniform. The present measurement method had a measurement error of -2.25 to 1.15 degrees C and it exhibited a similar level of shot-to-shot fluctuations (+/- 0.42-2.34 degrees C). This technique was used to measure the temperature in an optical engine and it gave reasonable temperature maps. (C) 2011 Elsevier Ltd. All rights reserved., PERGAMON-ELSEVIER SCIENCE LTD
INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER, Aug. 2011 - VISUALIZATION STUDY OF CAVITY TONE IN CLOSED TANDEM SIDE-BRANCHES USING A HIGH TIME-RESOLVED PIV TECHNIQUE
Yanrong Li; Satoshi Someya; Koji Okamoto, Flow-induced acoustic resonance in a piping system containing closed tandem side-branches was investigated experimentally in this study. Velocity perturbation was induced at the mouth of the cavity using two pumps and a block. An uncommon acoustic mode change, from a higher mode to a lower mode, was observed when the flow rate in the main pipe increased. This phenomenon was examined by high-time-resolved Particle Image Velocimetry (PIV). The instantaneous velocity field in a cross section was visualized two-dimensionally using PIV technique, simultaneously with the pressure measurement at multi-points around the cavity by microphones. The fluid flows at different points in the cavity interact, with some phase differences between them, and the relation between the fluid flows was clarified. The phase difference of the acoustic pressure fluctuation at different points around the cavity was also obtained. Consequently, phase delays of oscillation at different points were obtained two-dimensionally. 2-D phase map was helpful to discuss the feedback mechanism of the self-induced vibration. This is the first research which can obtain this kind contour map using the time sequential instantaneous velocity fields for closed tandem side-branches system which has long side-branches (LID >> 1) and high inflow velocity at high resonant frequency., AMER SOC MECHANICAL ENGINEERS
PROCEEDINGS OF THE 18TH INTERNATIONAL CONFERENCE ON NUCLEAR ENGINEERING 2010, VOL 3, 2011 - Combined two-dimensional velocity and temperature measurements of natural convection using a high-speed camera and temperature-sensitive particles
Satoshi Someya; Yanrong Li; Keiko Ishii; Koji Okamoto, This paper proposes a combined method for two-dimensional temperature and velocity measurements in liquid and gas flows using temperature-sensitive particles (TSPs), a pulsed ultraviolet laser, and a high-speed camera. TSPs respond to temperature changes in the flow and can also serve as tracers for the velocity field. The luminescence from the TSPs was recorded at 15,000 frames per second as sequential images for a lifetime-based temperature analysis. These images were also used for the particle image velocimetry calculations. The temperature field was estimated using several images, based on the lifetime method. The decay curves for various temperature conditions fit well to exponential functions, and from these the decay constants at each temperature were obtained. The proposed technique was applied to measure the temperature and velocity fields in natural convection driven by a Marangoni force and buoyancy in a rectangular tank. The accuracy of the temperature measurement of the proposed technique was +/- 0.35-0.40A degrees C., SPRINGER

Satoshi Someya; Joji Kuwabara; YanRong Li; Koji Okamoto, The phenomenon of flow-induced vibration of bluff bodies has been studied extensively. The vast majority of these studies have concentrated solely on one degree-of-freedom oscillation in the inline or cross-flow directions. Herein, experiments were carried out with a cylinder in a water channel with two degrees-of-freedom. The cylinder was cantilever mounted with a low natural frequency (typically 65 Hz) in the inline and cross-flow directions. The Reynolds number fell in the range 1.17 x 10(3) < Re < 2.6 x 10(4). The oscillating frequency of the cylinder and the surrounding flow were measured simultaneously using high temporal resolution particle image velocimetry (Ply), which is non-intrusive with respect to the flow and has high spatial and temporal resolutions. The vibration of the cylinder was found to be anisotropic. There was a discrepancy between the vibration frequencies in the inline and cross-flow directions, the difference being a function of reduced velocity. (c) 2010 Elsevier B.V.

TSParticles were synthesized using ion-exchange particles and Eu(TTA) luminescent dye. The size and material of the particles for synthesizing TSParticles are selectable. TSParticles respond to temperature changes in a flow and can also serve as tracers for the velocity field. TSParticles were seeded into a heated water flow in a complex-shaped channel constructed of MEXFLON resin, which has a refractive index exactly equal to that of water. Particle images of flow beyond the structure can be recorded without any distortion. The TSParticles were excited by the UV pulsed laser and the luminescence from the TSParticles were recorded at 40,000 frames per second as sequential images for a lifetime-based temperature analysis. Another advantage of our approach is that high time-resolved PIV can be carried out without a high-frequency laser. The recorded images were also used for the particle image velocimetry (PIV) calculation., SPRINGER

Ejection of jets from the top of the droplet was observed during the transient interaction between the droplet and a hot wall. We term this phenomenon jet ejection from droplets. When the bottom of the droplet initially impacts the hot surface, a jet is to be ejected from the top of the droplet. The jet ejection occurred only at low impact velocities and around the wetting limit temperature. It was not observed when droplets were dropped from large heights or when the surface was at a high temperature. © The Visualization Society of Japan 2009.
Journal of Visualization, Feb. 2010 - An experimental investigation of flow-induced acoustic resonance and flow field in a closed side branch system using a high time-resolved PIV technique
Yan Rong Li; Satoshi Someya; Koji Okamoto, Systems with closed side branches are liable to an excitation of sound known as cavity tone. It may occur in pipe branches leading to safety valves or to boiler relief valves. The outbreak mechanism of the cavity tone has been ascertained by phase-averaged pressure measurements in previous research, while the relation between sound propagation and the flow field is still unclear due to the difficulty of detecting the instantaneous velocity field. It is possible to detect the two-dimensional instantaneous velocity field using high time-resolved particle image velocimetry (PIV). In this study, flow-induced acoustic resonance in a piping system containing closed side branches was investigated experimentally. A high time-resolved PIV technique was used to measure the gas flow in a cavity. Airflow containing oil mist as tracer particles was measured using a high-frequency pulse laser and a high-speed camera. The present investigation on the coaxial closed side branches is the first rudimentary study to visualize the fluid flow two-dimensionally in a cross-section using high time-resolved PIV, and to measure the pressure at the downstream side opening of the cavity by microphone. The fluid flows at different points in the cavity interact, with some phase differences between them, and the relation between the fluid flows was clarified., SPRINGER

Satoshi Someya; Mitsunori Uchida; Kaoru Tominaga; Keiko Ishii; Yanrong Li and Koji Okamoto, A simultaneous measurement technique of velocity and temperature distribution in a fluid flow was developed. Particle image velocimetry (PIV) was combined with a lifetime based scalar measurement technique. A measurement method based on the luminescent lifetime is appropriate for detecting the transient temperature field. Developed method needs a high speed camera, a laser (one excitation wave length) and temperature sensitive particles (TSParticles). The luminescence from TSParticles doped with EuTTA was detected by the high speed camera, which was not equipped with any image intensifier, at 15 000 frames per second. Imaging at the high frame rate has a possibility to carry out PIV with a wide dynamic range. A decay of luminescent intensity was detected in detail. The decay curves at various temperature conditions were fitted well to exponential functions, from which the decay constant at each temperature was obtained.

Satoshi SOMEYA,Satoshi YOSHIDA,Yanrong LI,Koji OKAMOTO, It is known that flying fish perform long-range flight in the air in order to escape from predators such as tuna and swordfish. During the unsteady flight, ground effect enables the flying fish execute to flight for the maximum range and longest time. In this study, it was investigated a basic characteristic of the flow around the flying fish fin in ground effect, in order to understand the flying fish gliding performance quantitatively. The streamwise velocity profiles around the airfoil model were measured by a high time-resolved PIV (particle image velocimetry) in an open loop wind tunnel. A moving ground essential to generate the ground effect was supplied using a rotating disk. Two plates were put in tandem as the test wing model of a pectoral fin and a ventral fin of the flying fish. It was found that decreasing the height of the airfoil model caused a larger difference between the velocity in the suction surface side and that in the pressure surface side of the pectoral fin model., The Japan Society of Mechanical Engineers

Satoshi Someya; Satoshi Yoshida; Yanrong Li; Koji Okamoto, The velocity field and temperature distribution in a fluid flow were measured simultaneously based on luminescence. PIV is useful for velocity measurement, and a measurement method based on the luminescent lifetime is appropriate for detecting the transient temperature field. However, there have been few reports on thermometry in the fluid flow by luminescence, whereas several studies have investigated surface temperature measurement. The europium complex (EuTTA) has been commonly used in temperature-sensitive 'paints' for several years and consequently has been examined in several papers. In the present study, particles doped with EuTTA, called temperature-sensitive particles (TSParticles), were prepared. The optical properties of the TSParticles were investigated. A TSParticle was found to be suitable for use with an optical sensor because its lifetime is very sensitive to temperature changes. The lifetime of the TSParticle was approximately 600 mu s at 20 degrees C in water and the intensity was also large enough to be detected by a CCD camera without any image intensifier, at an exposure time of less than 60 mu s. It was found that TSParticles could also be used for velocity measurement by means of the PIV technique. The temperature field was measured based on the decay ratio of the TSParticle images, and the velocity distribution in the same plane was also evaluated from these images by PIV. A demonstration was carried out in a thermal stratified silicone oil bath. The velocity and the transient temperature distribution of the oil flow were successfully measured. The spatial resolution of the temperature measurement in the demonstration was 60 mu m. The uncertainty of the temperature was 0.35 degrees C. The spatial resolution and the uncertainty of velocity measurement were 0.6 mm and 20 mu m s(-1), respectively., IOP PUBLISHING LTD
