Application of methods of thermodynamics of irreversible processes to investigationofheat and mass transfer in a boundary layer

Abstract

This paper considers the process of heat and mass transfer in a boundary layer at evaporation of a liquid. In this case heat and mass transfer mechanism differs from the process of heat transfer without mass transfer. Experimental results obtained showed that in the boundary layer over a plate there were submicroscopic particles of liquid whose evaporation was going on in the boundary layer itself. On the basis of the theory of thermodynamics of irreversible processes methods of calculation of mass transfer with regard for the action of all the thermodynamic forces including also a new effect of separation of gas mixture components during the process of molecular transfer of kinetic energy of a regulated motion have been developed.
