The axisymmetric non-linear steady flow of a rarefied gas in a pipe of circular cross-section

The axisymmetric steady problem of the steady solution is formulated in a rectangular domain in the meridional plane of flow for the non-linear kinetic equation with model collision operator and is solved by the finite difference method with boundary condition of diffuse reflection from the side surface of the cylinder. Attention is mainly paid to flow from the vaporizing end into a vacuum. (C) 1997 Elsevier Science Ltd.
