Two dimensional transient motions of a vapor-gas mixture due to evaporation and condensation processes within a rectangular region have been considered with a view to grasping the effects of the presence of a noncondensable (inert) gas on the flow fields and their transition processes. Owing to the sudden change in temperatures of the condensed phases which are embedded in the solid boundary walls of the region, a flow takes place, and the development of this transient flow has been studied numerically based on the Boltzmann equation of BGK type for gas mixtures subject to the boundary condition of diffusive type appropriate for evaporation and condensation. The present results confirm those of the numerical analyses which have already been carried out based on the fluid dynamic formulation for binary gas mixtures established earlier in our laboratory.
