Flow boiling applied to the thermal management system in space attracts much attention as promising means to realize high-performance heat transfer and transport because of large latent heat of vaporization. In the present paper, effects of tube orientation on flow boiling heat transfer characteristics was investigated for FC72 flowing in a 0.51mm-diameter single mini-tube. In the entire range of tested mass velocity, heat transfer coefficients were influenced by vapor quality even under low vapor quality conditions in both of vertical upward and vertical downward flows. The boundary between the body force dominated and the inertia force dominated regimes was given by Froude number as Fr = 5, while the boundary between the body force dominated and the surface tension dominated regimes was deduced to be the relation by Bond number Bo <0.51., 形態: カラー図版あり, 共催: 日本学術会議, Physical characteristics: Original contains color illustrations, joint hosting: The Science Council of Japan, 資料番号: AA0064730018}, 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)}, title = {単一細管内沸騰二相流の熱伝達係数に対する力の支配領域の特定に関する実験的研究}, volume = {26}, year = {2010} }
