Краткое описание

Results of an analysis of turbulent heat and mass transfer in a boundary layer during the condensation of gas-vapor mixture are submitted in this paper. It is assumed that the gas-vapor boundary layer has the maximal thermal resistance to heat transfer, and the condensate film is perpetually taken off through a wall. The system of integral equations for the turbulent boundary layer of two-component gas mixture with one-component selective sucking through the wall is solved. The analogue between heat and mass transfer processes is used for solving the problem. The influence of noncondensing admixture concentration and the degree of vapor overheating in the flow core on heat fluxes and mass flows is analyzed for the mixture of water vapor and air. Comparisons with results of Sparrow et al. [13] and Minkowyczet al. [10] for condensation of gas-vapor mixture under the condition of a forced convective overflow are presented
