摘要：

Several boiling regimes are characterized by intermittent contacts of vapor and liquid at the superheated wall surface. A microthermocouple probe was developed capable of detecting transient surface temperatures with a response time better than 1 ms. The transient temperature data were utilized to determine the time-varying heat flux under liquid contacts. The instantaneous surface heat flux was found to vary by orders of magnitude during the milliseconds of liquid residence at the hot Surface. The average heat flux during liquid contact was found to range from 10(5) to 10(7) W/m(2) for water at atmospheric pressure, as wall superheat was varied from 50 to 450 degrees C.
