DRY SPOT RADIUS AND MICROFILM THICKNESS BENEATH A VAPOR BUBBLE
1991
A simplified mechanism of energy supply to a bubble growing in a heterogeneous system is considered. The model described is based on approximate mass and energy balance equations for the evaporating portion of the microfilm and the vapor in the bubble. It will be assumed that the energy demand through the interphase boundary of the bubble cupola and the remaining portion of the microfilm can be neglected. Solutions of the equations presented satisfactorily describe available experimental data on microfilm thickness and dry spot radius.
