摘要
The paper presents the results of solving the problem of liquid evaporation and its vapor condensation in a closed space with regard to the formation of droplets in it as a result of homogeneous vapor nucleation, obtained by jointly solving the Boltzmann kinetic equation and the equations of continuum mechanics. The kinetics of homogeneous vapor condensation is described by the corresponding system of moment equations. Calculations for water have shown that in the case where the evaporation surface temperature exceeds 330 K, volume condensation of vapor occurs with high intensity, which leads to significant changes in the profiles of its parameters.
