Boiling and Two-phase Flow in Channels with Extremely Small Dimensions --- Review of Japanese Researches
View Abstract (pdf format)

Brief Bio

Since 1981 Prof. Ohta has been involved in heat transfer activities in Department of Mechanical Engineering, Kyushu University, where he investigated the effects of pressure, surface roughness, and mixture concentration on nucleate boiling. From 1990 to 1991 he stayed in the laboratory of Prof. Straub, Technical University of Munich, and started new investigation, i.e., microgravity boiling and two-phase flow. He became PIs in several Japanese projects including microgravity flight experiments and clarified, for example, the effect of gravity on two-phase forced convection by using transparent heated tubes. After he moved to Department of Aeronautics and Astronautics, and became a professor in 1999, he reinforced the collaboration with Japanese space agency JAXA (NASDA) and started the development of two-phase loop systems and cold plates for the waste heat management in space platforms of enlarged size. .
