APPROXIMATION METHOD OF CALCULATING THE EFFECT OF DIFFUSION UPON THE HEAT CONDUCTION OF GASES IN A BOUNDARY LAYER

Abstract

The effect of the diffusion of vapors of an adiabatic vaporable liquid is considered, with respect to the heat exchange between it and surrounding hot gas on the basis of the molecular and kinetic concept of the device of heat conduction. By means of simplified calculations which bear a preferably qualitative char-ACTER, IT IS SHOWN THAT THE DIFFUSION FLOW OF A VAPORABLE SUBSTANCE - POSSESSING A DIRECTION OPPOSED TO HEAT FLOW - CONTRIBUTES TO A DECREASE IN HEAT EXCHANGE INTENSITY IN CONSEQUENCE OF A DECREASE IN THE HEAT CONDUCTION COEFFICIENT OF THE BOUNDARY LAYER.
