The Chair welcomes the visitor of Professor Yasuyuki Takata from the International Institute for Carbon-Neutral Energy Research (I2CNER), Kyushu University, 16-17 March 2025.
Professor Takata is a Specially-appointed Professor at International Institute for Carbon-Neutral Energy Research (I2CNER), Kyushu University. He is also Professor Emeritus at Kyushu University and Honorary Professor at the University of Edinburgh. He was a Professor in the Department of Mechanical Engineering, Kyushu University until March 2022. His research interests include two-phase flow and heat transfer, thermophysical properties of hydrogen at ultra-high pressure, micro refrigerator and micro heat transfer device and numerical simulation of thermal and fluid flow. He was the Presidents of Heat Transfer Society of Japan (HTSJ) from 2019 to 2020 and Japan Society of Thermophysical Properties in 2016. He served as the President of the Asian Union of Thermal Science and Engineering (AUTSE) from October 2020 to September 2022. He received numerous awards including the JSME Thermal Engineering Achievement Award in 2010, and ASME ICNMM2018 Outstanding Leadership Award in 2018 and Heat Transfer Society Award for Scientific Contribution in 2022. He is a Council Member of the Science Council of Japan since October 2020.
Prof. Takata delivered a lecture titled Thermal Problems of Hydrogen at High Pressures. In the lecture, he presented first an overview of gas H2 storage for the commercial fuel cell vehicle (FCV) in Japanese market. Concerning the current FCV has 5kg of hydrogen at 82MPa in tank pressure, many thermal problems exist. Prof. Takata then presented his own research in the last two decades regarding, the high pressure thermophysical properties of hydrogen up to 100MPa and 500°C and the establishment of a data base, as well as some typical thermo-technical problems with hydrogen refueling process are introduced in the presentation.
The topic is of high interest and relevance to our hydrogen work.
