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