Research Abstract |
Rewetting on a hot surface is an essential phenomenon governing inception of rapid cooling with boiling heat transfer. A fast response local surface temperature measurement technique has been developed to capture the transient boiling heat transfer during impact of a single ethanol droplet on a hot surface being much higher than the boiling temperature. Typical liquid-solid contact time is below 10 milliseconds. Transient boiling heat transfer processes with/without rewetting phenomenon were elucidated with visual observations by a high speed video camera synchronized with the local heat transfer measurement.
