Для численного исследования пульсирующей детонационной волны в рамках двухстадийной модели кинетики химических реакций в системе координат, связанной с фронтом лидирующей волны, разработан оригинальный вычислительный алгоритм. Для четырех известных режимов распространения детонации в рамках данной модели исследовано влияние порядка аппроксимации алгоритма, длины расчетной области, сеточного разрешения и типа граничного условия на дальней границе на результаты моделирования. Проведено сравнение характера пульсаций с результатами расчетов других авторов. For the numerical study of a pulsating detonation wave using a two-stage kinetics model of chemical reactions in the shock-attached frame, a new numerical algorithm is proposed. For the four known modes of detonation wave propagation, the effect of the approximation order of the proposed numerical algorithm, the length of the computational domain, the grid resolution, and the type of the farfield boundary condition on the simulation results is analyzed in the framework of this model. The character of pulsations is compared with the numerical results obtained by a number of other authors.

Abstract The paper contributes to the clarification of the mechanism of one-dimensional pulsating detonation wave propagation for the transition regime with two-scale pulsations. For this purpose, a novel numerical algorithm has been developed 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 has been studied for four main regimes of detonation wave propagation for this model. Comparison of dynamics of pulsations with results of other authors has been carried out.
