Abstract

A helium flow in the enclosure caused by a sudden heating of the enclosure walls is considered. The Boltzmann equation and the non-stationary Navier-Stokes equations with corresponding boundary conditions are numerically integrated. The calculation results for a steady flow are shown to be close.
