Two-dimensional direct Monte Carlo simulation of the flow around an evaporating water microdroplet in the air atmosphere above a dry or liquid surface has been carried out. We consider a cylindrical droplet 1 μm in diameter at a distance of 1 μm above the surface. The temperature of the droplet is taken equal to 65°C and 80°C. A significant decrease in the air concentration between the droplet and the liquid film surface is observed. The features of water vapor flow separately from the droplet surface and from the liquid film surface are considered. It is shown that, under certain conditions, condensation on the lower side and evaporation on the upper side on the droplet can occur simultaneously.
