Abstract
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.
