Abstract

The article presents numerical simulation results for the problem of tungsten vapor propagation after its evaporating from a surface heated with a high-speed electron beam. The model is based on solving the system of gas dynamics equations written in divergence form. The resulting system of equations is implemented via the Belotserkovskii large-particle method. The density and vapor temperature distributions are obtained for a surface heated up to a temperature of 8000 K. Calculations show that the normal temperature distribution on the specimen surface results in a noticeably spherical shape of the gas exit front.
