Numerical simulation of heterogeneous detonation in polydisperse gas suspensions using modern parallel computational architectures

Modification of the serial Fortran code for solving unsteady 2D Euler equations for the mixture of compressible gas and polydisperse particles was carried out using OpenMP technology. Parallel code was used for the numerical simulation of shock wave propagation in 2D channel with obstacles filled with reactive Al-O2 gas particle mixture. Analysis was shown that obtained parallel speed-up is in a good agreement with the Amdahls law, which gives the estimate for serial code fraction about 30%
