摘要

The steady-state liquid temperature profile for a liquid filled conical cavity containing entrapped gas has been developed to show the existence of a region of uniform superheat within the cavity; a condition required for correct application of the classical nucleation equations. Experiments performed to obtain numerical values for the effective nucleus radius show that the nuclei must attain their critical size within the extreme lower recesses of the sites. Additionally it is shown that the nuclei do form well within the region where the liquid is uniformly heated to the temperature of the cavity wall.
