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 a system of gas dynamics equations written in a divergent form. The resulting system of equations is implemented via the Belotserkovsky large particle method. The distributions of density and temperature of vapors are obtained for a surface heated up to temperature of 8000 K. Calculations show that normal temperature distribution on the sample surface leads to a noticably spherical shape of the gas exit front.
Keywords: mathematical modeling, gas dynamics equations, large particle method, computational experiment, tungsten erosion. .
