Parallel Algorithm for Calculating the Dynamics of Tungsten Vapor Distribution

Abstract

We consider an extended dynamic model of tungsten vapor distribution when the surface of a tungsten sample is heated by an electronic beam pulse. The parameters of the model are taken from the experiments on the Beam of Electrons for materials Test Applications (BETA) stand. This stand was designed in the INP SB RAS. The temperature in the sample is calculated from the two-phase Stefan problem. The temperature on the surface of the sample is taken as a boundary condition for the system of gas dynamics equations. A case of axial symmetry is considered. A parallel version of the algorithm, implemented using OpenMP technology, is presented.
