Vapor Condensation at Sudden Contact With Cold Liquid in Non-Equilibrium Conditions

Condensation of saturated vapor at sudden contact with cold liquid was studied with use of numerical solution of the Boltzmann kinetic equation. Results were obtained for both constant and variable temperature of liquid. In the first case vapor condensation becomes stationary after very small time; in the second one this process can not be stationary due to used model of heat transfer in liquid. Possibility of use of stationary kinetic correlations was estimated. For both cases results of numerical solution are in good agreement with correlation proposed by D.A. Labuntsov and A.P. Kryukov. Therefore, this correlation can be used as non-equilibrium boundary condition at solution of applied problems.
