Journal of Thermal Science and Engineering Applications 16(2) 021005 (11 pages) 2023年11月16日 査読有りAbstract 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.

日本機械学会関東支部総会講演会講演論文集 2016(22) "GS0607-1"-"GS0607-2" 2016年3月10日This 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.

熱工学コンファレンス講演論文集 2015 "B133-1"-"B133-2" 2015年10月23日This study involved conducting 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, boiling curve. 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.

熱工学コンファレンス講演論文集 2015 "C142-1"-"C142-2" 2015年10月23日An 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.

年次大会 : Mechanical Engineering Congress, Japan 2015 "G0600101-1"-"G0600101-3" 2015年9月13日In 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.

流体工学部門講演会講演論文集 2010 309-310 2010年10月29日The 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.

日本流体力学会年会講演論文集 2010 234-234 2010年It 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.

流体工学部門講演会講演論文集 2009 605-606 2009年11月6日The 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.
