International Symposium on Transport Phenomena, or ISTP is organized by PCTFE (Pacific Center of Thermal-Fluids Engineering) founded by Prof. W. J. Yang (University of Michigan) 1985. ISTP was already held 32 times during 37 years (1985-2022). Details of the past ISTP can be found at

Especially these couple of years, ISTP-31 and ISTP-32 have been successfully conducted as full-online events in spite of the hard situation under COVID-19 pandemic. With the great respects and appreciations for chair persons and organizing committee members of each ISTP in the past, the 33rd ISTP will be held in Kumamoto, Japan, 2023 as a face-to-face event once again.
