В данной работе представлены некоторые результаты трехмерного числительного моделирования процессов, возникающих в химически реагирующей водородно-воздушной смеси совершенных газов после отражения и фокусировки падающей ударной волны от клинообразной вставки. В зависимости от интенсивности набегающей на вставку ударной волны выявлено несколько различных сценариев возникающих процессов и определены условия возникновения детонации. Также представлено тестирование результатов численного моделирования путем сравнения с экспериментальными данными.

The article presents some results of three-dimensional numerical simulations of processes in chemically reacting hydrogen-air mixture of ideal gases after reflecting and focusing of a shock wave against a wedge. Depending on the intensity of the shock wave, several different scenarios of emerging processes are obtained, and the conditions for detonation onset are determined. Comparisons of numerical simulations results with experimental data are also presented.
