PTVによる液液二相流の水滴界面近傍の流動計測 PTV Measurement at Close Region to Interface of a Water Drop in Oil 山内, 慎 70029536 植村, 知正 Uemura, Tomomasa 植村 Uemura 知正 Tomomasa 60112009 小澤, 守 Ozawa, Mamoru 小澤 Ozawa 守 Mamoru open access Water Drop in Oil Oil-Water Interface PTV Velocity Distribution Close Region to Surface Inner Flow Velocity distributions adjacent to the interface between a water-drop and surrounding oil were measured using PTV. By analyzing the measured velocity data the physical properties such as surface slip conditions, circulating flow in a drop, distributions of contamination skin, are quantitatively obtained. Relating to the heat and mass transfer in multi-phase flows, information about microscopic phenomena occurred at the interface of fluids has been estimated so far from macroscopic measurements. Difficulties to directly measure the phenomena on the interface come from their special conditions of moving boundaries, transient, and spatially distributed phenomena. Most of those difficulties can be resolved by the PTV technique. Since it is the quantitative visualization method, only if some of those phenomena can visually captured, it is not difficult to obtain a part of the required information. 日本混相流学会 2000-12-15 jpn journal article VoR http://hdl.handle.net/10112/4957 https://kansai-u.repo.nii.ac.jp/records/11159 AN10088286 09142843 混相流 14 4 466 472 https://kansai-u.repo.nii.ac.jp/record/11159/files/KU-1100-20000900-09.pdf application/pdf 3.1 MB 2019-05-23
