Flows of two-component mixtures with vapor condensation 
on cooled surfaces are analyzed by the methods of molecular-kinetic 
theory. The mixture contains a noncondensable component whose average 
density remains constant in the region under study. The influence 
of the gas on the process of recondensation of the vapor and the interaction 
of the components of the mixture in the cases of equal and different 
molecular weights are studied. The problems posed are investigated 
using the method of direct numerical solution of the kinetic Boltzmann 
equation modified for the mixture of gases. Special emphasis is placed 
on compution of direct and cross collision integrals.
