Intense evaporation from the surface of a spherical particle into a vacuum with due regard for the evaporation coefficient

The problem on intense evaporation of a spherical particle into a vacuum at small values of the Knudsen number is treated. The case of incomplete accommodation of molecules colliding with the evaporation surface is analyzed. Analytical expressions are derived for calculating the vapor parameters at the hydrodynamic limit of evaporation, and their dependence on the evaporation coefficient $\alpha$ is investigated.
