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.

热表面上的再润湿是控制沸腾传热快速冷却开始的基本现象。开发了一种快速响应局部表面温度测量技术，用于捕获单个乙醇液滴撞击远高于沸腾温度的热表面期间的瞬态沸腾传热。典型的液固接触时间低于 10 毫秒。通过与局部传热测量同步的高速摄像机的目视观察，阐明了有/没有再润湿现象的瞬态沸腾传热过程。
