Представлены результаты численного моделирования процесса перехода горения во взрыв в образцах взрывчатого вещества LX-10, заключенных в прочную сборку. Расчеты проведены в программе конечноэлементного анализа ANSYS Autodyn с использованием модели горения Powder Burn. Получено удовлетворительное соответствие расчетных и экспериментальных данных. Ключевые слова: горение, взрыв, ANSYS Autodyn, скорость разлета.
The paper introduces a method for determining kinetic parameters for the pressed explosive tetranitropentaerytrite. This method includes analytical dependence for the period of induction, which is used to process the experimental data, and the ANSYS CFD finite element analysis software package. The found values of the kinetic parameters made it possible to obtain a satisfactory agreement between the calculated and experimental ignition distances for pressed tetranitropentaerytrite
