Nonsteady evaporation and growth of drops in gas(EOUS) medium

The process of heat and mass transfer during the evaporation or condensational growth of single drop in gas is investigated in quasistatic approach. The convection and diffusion in gas and heat conductivity in gas and drop are taken into account. For single drop in infinite gas medium the new analytical solution, which describes the asymptotic quasi-steady regime of phase transfer is obtained. There is the discussion of the numerically obtained distributions of the temperature and concentration and the laws of phase transfer and pressure change for particle in finite and infinite medium.
