Boundary value problems for the ellipsoidal statistical equation. (Russian) Zbl 1071.76048
The article is devoted to studying the so-called half-space boundary value problems for the ellipsoidal statistical equation with the collision frequency $$\nu = \nu_0V$$, where $$V$$ is the molecular velocity modulus which arises in the context of the kinetic theory of rarefied gas flows. The main aim of the article is to present a method for analytical solution of the above-mentioned boundary value problems. As a result, the authors obtain a solution to the classical Smoluchowski problem on the temperature jump and weak evaporation in a rarefied gas. Moreover, formulas for calculating the temperature jump and the concentration are presented. Numerical representations of the formulas obtained make it possible to determine the coefficient $$C_t$$ of the temperature jump and to perform a comparison with previous results.
