The paper is devoted to numerical simulation of multicomponent gas flows based on extended Euler equations using a modified explicit Godunov-type scheme. A feature of the used algorithm is to take into account strong shock waves and occurrence of pressure oscillations at contact boundaries. This is expressed in using the exact solutions of the corresponding Riemann problem and special double-flux modification of Godunov-flux. Numerical simulation results demonstrate the robustness of present method and good agreement with the one- and two-dimensional test data of other groups and laboratory experiments.
Keywords: multicomponent gas dynamics, double flux method, Godunov method.
