The authors develop a novel numerical algorithm for the numerical investigation of the gaseous pulsating detonation wave using the two-stage model of kinetics of chemical reactions in the shock-attached frame. The influence of grid resolution, approximation order, and the type of rear boundary conditions on the solution have been studied for four main regimes of detonation wave propagation for this model, namely high frequency, very high, low frequency, and transition regimes. A comparison of dynamics of pulsations with previous result has been also carried out.
