Abstract :
The numerical calculation heat- and mass transfer of a flow containing dispersed in liquid particles by a diameter 1...1000 microns is executed under normal physical conditions for laminar flow of a mode of. As a results of calculations the temperatures (gas vapour mixture and droplets), diameter of a drop both mass concentration vapour and liquids were defined. The decision includes distribution of temperature air-vapour flow and drops of a liquid in a boundary layer and takes into account evaporation of drops. The results of calculations on model for single-phase current coincide with well-known results of analytical and numerical calculations. The comparison of the developed model of numerical heat- and mass transfer with theoretical works, available in this area, is made and the satisfactory coordination is received
