University of Fukui Faculty of Engineering, Division of Engineering, Mechanical Engineering Professor

Profile

  1. ･My major research topic is "boiling". Especially, I'm doing researches on 1) revealing of quenching condition, i.e. initiation of wetting, during cooling of high temperature surface by boiling, and 2) making database of boiling heat transfer and developing better prediction methods including machine learning.
    ･My lecture topics are engineering thermodynamics, heat transfer engineering and etc.
    ･I was born and brought up in Ishikawa Pref., and spent university student's days in Tokyo. 31 years have passed since I moved to Fukui. My hobby is "Go".
