Abstract

Numerical simulations of detonation wave propagation in a channel are performed and the formation of the detonation wave multifront structure is studied. An in-house numerical code running on hybrid supercomputers is employed for the numerical simulations. The code is written in C++ with the use of MPI, OpenMP and CUDA parallel technologies. Four different chemical reaction mechanisms for description of hydrogen/oxygen mixture combustion are considered. The mechanisms are compared in terms of the Chapman-Jouguet detonation speed, the predicted number of detonation cells and the shape of detonation wave front.
