Heat transfer for film condensation of vapour

Abstract

Study provides an analysis of the heat transfer for constant heat flux densities across the film. A situation of this type is observed with film condensation. The analysis of film condensation includes the distribution of mean heat transfer coefficient and of heat flux density along the height of condensation surface. It has been determined that the mean heat transfer coefficient does not depend on the nature of condensation temperature variation. Semi empirical relationships evaluating the temperature gradient are suggested.
