The applicability of the S-model kinetic equation for simulation of evaporation and condensation phenomena is investigated by comparing its results for Argon with those of Molecular Dynamics(MD). The steady-state evaporation and condensation between two liquid Argon layers, kept at different but constant temperatures, is simulated. The temperature ratio between the hot/cold Argon layers is fixed at and the rarefaction parameter is equal to , which corresponds to the beginning of transitional flow regime. The macroscopic profiles of temperature and heat flux in vapor between the liquid layers are depicted. Both methods predict an inverted temperature profile. The agreement between the methods depends on the evaporation/condensation coefficients and the temperature at the liquid boundaries. Therefore, it is important to obtain the evaporation/condensation coefficients and the positions of the liquid boundaries accurately.
