Journal of Thermal Science and Engineering Applications, 16(2) 021005 (11 pages), Nov 16, 2023 Peer-reviewedAbstract This paper presents an experimental investigation of local heat transfer characteristics of single-phase flow in a plate heat exchanger (PHE). The local heat transfer coefficient is evaluated using a test section with PHE geometry for measuring wall temperature distribution. The test section of 1.5 mm thickness is employed to consider the heat conduction effect of the heat transfer plate. The results indicated that the local heat transfer coefficient is influenced by the development of the thermal boundary layer along the flow direction and the maldistribution of water flows along both the direction perpendicular to the flow and the stacking direction. The harmonic mean heat transfer coefficient calculated by the measured local heat transfer coefficient agrees with the average heat transfer coefficient evaluated by the modified Wilson plot method within ±25% and within ±16% for the hot side and the cold side, respectively.

2016(22) "GS0607-1"-"GS0607-2", Mar 10, 2016This paper deals with subcooled flow boiling experiments using various different dissolved air concentrations in the Perfluorohexane (PFH) in order to clarify its effects on flow boiling heat transfer through a tube with an inner diameter of 4 mm, the following parameters were calculated and discussed: excess temperature and boiling curve. As a result, dissolved air was shown to affect boiling characteristics. In particular, dissolved air significantly affected the boiling curve in the low heat flux region, and the boiling curve was continuously decreased with increasing the effective heat flux for mass flux of 300 kg/(m^2s). Dissolved air significantly also affect the onset of boiling. These effects lead to increasing generation of bubble.

Consequently, dissolved air was shown to affect boiling characteristics. In particular, dissolved air significantly affected the boiling curve in the low heat flux region, and the boiling curve was continuously decreased with increasing the effective heat flux for G = 300 [kg/m^2s], respectively. Also dissolved air significantly affect the onset of boiling.

Procee[d]ings of Thermal Engineering Conference, 2015 "C142-1"-"C142-2", Oct 23, 2015An exhaust heat recovery system using exhaust gas discharged from the factory is effective method for the energy problem. However, particles which deposited in the duct of the exhaust heat recovery system decrease heat transfer because these exhaust gas contains many fine particles. The purpose of this research is assessment of dust deposition in the exhaust heat recovery system. As an effective method, the flow field, temperature distribution and particles deposition height in the duct are analyzed by CFD. In this paper, the analytical results which was placed rectangular plate in the duct are shown.

Mechanical Engineering Congress, Japan, 2015 "G0600101-1"-"G0600101-3", Sep 13, 2015In this paper,the heat transfer enhancement of the vortex generator is investigated by the numerical analysis using the STAR-CCM+ commercial software. Vortex generator is installed in a rectangular channel, the shape of the vortex generator are trapezoidal, triangular and rectangular. The analytical conditions, Reynolds number based on the trapezoidal fin height is 2500, Prandtl number of the fluid is 0.71. Performance of the vortex generator was evaluated by bulk mean temperature gradient and pressure gradient from the channel inlet to outlet. Three shapes of the effective vortex generator are compared and it has shown the relationship of the the vortex structure generated by the vortex generator and the Nusselt number.

Fluids engineering conference ..., 2010 309-310, Oct 29, 2010The purpose of this study is to compare characteristics of flight motion between straight flapping motion and natural one. In order to understand the basis of lift and thrust generation, the finite difference method based on the ALE method is employed. Computation are performed for various flapping and feathering phase angles between the move like drawing figure-eight and straight translation motions. Time history of the unsteady force compared each other. Moreover, we survey the effect of Re, flapping frequency, feathering angle on fluid force in two flapping type.

2010 234-234, 2010It is well known that propulsion produced by caudal fin of aquatic animals have high efficiency. In order to investigate the propulsion of oscillating caudal fin, many study have been done experimentally and theoretically. In this study, the arbitrary Lagrangian-Eulerian method applied for the Navier-Stokes equation to simulate self-propulsion of carangiform. However, there is a few study that attention to the turning motion of fishes. Numerical simulation of turning motion is performed by asymmetric oscillation with respect to camber line.

Fluids engineering conference ..., 2009 605-606, Nov 6, 2009The fluid-structre interaction problems is important not only for the mechanical engineering problems like a flutter of an airfoil but also for the bioengineering problems like the blood flow in a blood vessel. For the flow analysis at the high Reynolds number of these problems, the method, the object can move freely in the fixed grid, highly affects the precision of the fluid analysis and elastic analysis by having the low resolution of the boundary layer. Therefore, we propose the boundary fitted fluid-structure interaction method and apply to analyze the flow around an oscillating elastic foil. As a result, it is possible to obtain the stable solution of the fluid analysis and elastic analysis. And It is clear about the characteristics of the unsteady fluid dynamics for the flow around the oscillating elastic foil.

Procee[d]ings of Thermal Engineering Conference, 2007 299-300, Nov 23, 2007For the detail study on forced convective boiling heat transfer in mini- and micro-tube, we developed the transparent heated mini- and micro-tube by electroless deposition. The inner wall of the tube is coated with the thin gold film, which allows the visualization of fluid motion. At the same time, the film resistance derives the temperature measurement of the inner wall of the tube. As a result of forced convective boiling experiments by using the tube with 1mm of inner diameter, the fluctuation of the inner wall temperature was caused by the boiling bubble departure from the tube wall, and its frequency was increased with heat flux increasing.

Fluids engineering conference ..., 2007 "G1201-1"-"G1201-4", Nov 17, 2007The understanding of the physics of flapping flight has long been limited due to the obvious experimental difficulties in studying the flow field around real living thing. In this study the three-dimensional numerical simulation based on non-inertia reference was performed. The object motion is computed by the momentum equation using pressure calculated by the flow computation. And two-dimensional velocity field around the flat plate swinging of pendulum was measured quantitatively. We show that the data can be used for quantitative studies, such as lift and drag prediction.

Fluids engineering conference ..., 2007 "G303-1"-"G303-4", Nov 17, 2007In recent years, commercial software is often used for a design process of fluid machine having a complicated structure. According to this method, the predicted performance was not achieved due to the bad quality solution. In order to authorize the computational accuracy, velocity field with large separation computed by commercial software was compared with measured value by the PIV method. The purpose of this investigation is to show the indication of how to use of the computational method by the commercial software in design process. As the results of this investigation, a quantitative comparison of numerical and experimental result was able to be confirmed in the low Reynolds number area.
