Abstract:

Methods of calculating processes of intensive evaporation in conditions where the vapor flux density j is limited by the evaporation kinetics and the heat supply have been considered. A convenient approximation of the superheat dependence of j based on the continual theory of a pressure jump stopped by a counter flow at the interface has been obtained. It has been found that a pressure jump may be assumed to be isoentropic with a sufficient accuracy, which simplifies the calculations considerably. It is shown that calculations of the process of intensive evaporation by a continual model, without invoking molecular kinetics, practically coincide with calculations by the kinetic evaporation theory. A simple criterion of transition from the regime limited by the evaporation kinetics to that limited by the heat supply has been suggested from conjugation at the interface of heat and mass flows.
