Research Outline

Effect of wettability and surface structure on boiling

Development of enhanced boiling heat transfer surface with low ONB* by making use of anodization and wettability control

*ONB: Onset of Nucleate Boiling

Boiling of ethanol on the enhanced surface
Mechanism of quenching in spray cooling

Seeking the mechanism of rapid cooling by analyzing behaviors of individual droplet at the hot surface.

Research Methods and Facilities

Boiling heat transfer surface with nano-scale re-entrant cavities

Development of high-performance boiling surface with 20-200nm pores by anodization for ethanol and HFE7100.
※Collaboration with UACJ

Analysis of spray cooling performance by control of cooling environment

The apparatus enables experiment up to 5 bar under various gas environment.Formation of oxide later of the sample surface is controllable.
