For 1-Propanol/Water and 2-Propanol/Water, increase in the heat transfer coefficients was confirmed while the critical heat flux values are decreased at very low concentration of alcohol. The existence of Marangoni effect on the observed heat transfer enhancement was emphasized. A definition of Marangoni number was proposed to take account of the Marangoni effect by using the concentration difference between vapor-liquid interface underneath bubble and bulk liquid., 形態: カラー図版あり, 資料番号: AA0064297120}, 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 = {宇宙用高性能冷却システムの開発を目的とした混合媒体の核沸騰における伝熱促進効果に関する研究}, volume = {25}, year = {2009} }
