Many experimental and theoretical efforts have been devoted to achieving a two-fluid model, which is one of the most popular models for industrial use. Such a model consists of individual mass, momentum, and energy conservation equations for two-phase flow, using an accurate description of the interfacial area transport or interfacial area concentration and the drive force acting on the gas-liquid interface. In this research, a basic database was obtained by measuring interfacial area transport under micro- and normal-gravity environments, using the drop-shaft in the Micro-Gravity Laboratory of Japan (MGLAB). The database showed the proposed model accurately predicted the relative velocity between bubble and liquid flow in the channel even in micro-gravity condition, and the estimated weight caused by the frictional pressure loss should be taken into account in the interfacial area transport and drift velocity., 資料番号: AA0063349020}, pages = {76--79}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {宇宙空間における気液2相流界面積濃度輸送機構解明に関する研究}, year = {2007} }
