Simulation results of the multifront cellular structure of a detonation wave in dilute hydro gen-... more Simulation results of the multifront cellular structure of a detonation wave in dilute hydro gen-oxygen mixtures are described. The aim of the present work is to assess the sensitivity of two dimensional simulations to the parameters of the two stage model of hydrogen-oxygen combustion, which determine the chemical kinetics of heat release. Based on the results of the simulations, it is proved that the modification of the two stage model of hydrogen-oxygen combustion put forward previously, as well as the method for evaluating its parameters are necessary in practical applications to provide realistic simulation of detonation waves in dilute hydrogen-oxygen mixtures.
