N2 - The present study deals with the onset of nucleate boiling (ONB) of a superheated liquid due to rapidly heated Micro-Heater (MH) at one atmosphere. A set of experimental results of ONB in HFE-7100 as a result of different heating rates will presented. There are very few studies and thus very scarce amount of data pertaining to rapid heating of HFE-7100 in the literature. In real liquids, namely liquids that are not specially treated for the removal of possible nucleation sites (such as dissolved gasses, suspended particles etc.), a high level of superheating may be obtained using high heating rates such that the liquid’s nucleation temperature is substantially higher than its saturation temperature. Prediction of superheat levels and nucleation temperatures under these conditions as a function of temperature change rate has not been possible with analytic tools up to recently. The present study aims at broadening the experimental data base, in order to gain more understanding on the ONB phenomenon due to rapid heating under various heating rates.
