We have been exploring boiling heat transfer mechanisms using MEMS thermal sensor and fast IR thermography. These high-resolution thermal measurement techniques allow direct access to the micro-scale fundamental heat transfer phenomena in the nucleate boiling, such as evaporation and dry-out of the microlayer, rewetting of the dry-patch and the heat transfer at the three phase contact line. The findings obtained through the fast local thermal measurement leads to better understanding of the boiling mechanisms. Also the precise local wall temperature is useful as the benchmark data for direct
numerical simulations. This talk will focus on open questions in boiling found through the high-resolution experiments for future better collaborations with PSI researchers.

Bio: Dr. Yabuki is an Associate Professor of Mechanical and Control
Engineering at Kyushu Institute of Technology in Fukuoka Japan. He is
leading Thermal Device Lab, where one PhD, 12 Master and 12
undergraduate students study. His research focuses on boiling flow, in
particular to micro-scale phenomena using high-resolution measurement
techniques.
