Description

A method for analyzing space-time profiles of the mass velocity U(h,t) is proposed and implemented. The method of analysis is based on the integration of the system of equations of conservation laws in Lagrangian variables. The method is implemented for the experimental data on the initiation of the PBX9502 explosive and all values of the gas-dynamic quantities are obtained, which will make it possible to refine the equations of state when solving problems of shock-wave compression of energy materials

Abstract (Russian)

Предложен и реализован метод анализа пространственно-временных профилей массовой скорости U(h,t). Метод анализа основан на интегрировании системы уравнений законов сохранения в лагранжевых переменных. Метод реализован для экспериментальных данных по инициированию взрывчатого вещества PBX9502, и получены все значения газодинамических величин, что позволит проводить уточнение уравнений состояния при решении задач об ударно-волновом сжатии энергетических материалов
