Kinetics of vapor condensation on a spherical particle in a dense gaseous atmosphere

Slow vapor condensation on a spherical particle in an atmosphere of noncondensing gas in the case of arbitrary temperature differences is investigated. It is assumed that the concentration of gas molecules in the vapor-gas mixture consisting of Maxwellian molecules significantly exceeds the vapor concentration. The problem is considered in the quasi-stationary approximation in the case of an immobile phase interface, and the results are obtained by using the Lees method (1965) to solve the kinetic equations with collision integrals in the Boltzmann form. Spatial distributions of density and temperature of the components of the vapor-gas system are obtained for various gasdynamic conditions.
