Abstract
The behavior of rewetting on a high superheated and dry surface, focusing on rewetting temperature just as collapse of saturated and subcooled film boiling was investigated experimentally and analytically. Saturated and subcooled impingement jet experiments were conducted by using a Silicon wafer with 20mm length, 20mm width and 0.5mm thickness and pure water at atmospheric condition. Temperature of the test heater was measured by using a commercial separated-type infrared thermometer from a back side of it. The present experimental results showed that as the liquid subcooling was high, MHF temperature was higher. Namely, the experimental results agreed with Dhir-Purohit's correlation.
