Mathematical Modeling of Detonation Initiation in the Channel with a Profiled End Using Parallel Computations

The paper is devoted to a numerical study of detonation initiation in the gas mixture channel with profiled end. Initiation occurs as result reflection shock wave relatively low intensity from end channel. Numerical calculations are carried out using unstructured triangular grids. algorithm parallelized by computational domain decomposition method METIS library. exchange grid function values between computing cores performed MPI conducted on grids different numbers cells. Detonation patterns obtained, which correspond each other. differences mainly related degree resolution elements flow
