This article presents the results of the analysis of the applicability of the quasi-one-dimensional calculation of the main gasdynamic processes in a reflected shock tunnel for the tasks of experiment planning. Estimates of the test time, duration of the nozzle start-up, and parameters of the supersonic gas flow at the point of model installation are obtained. Results of the calculation were compared with measurements carried out on the Large Shock Tube of the Ioffe Institute. The applicability of 1D approach has been shown.

Анализ применимости квазиодномерного подхода для определения газодинамических параметров в ударной трубе с отражающим соплом

Представлены результаты анализа применимости квазиодномерного расчета основных газодинамических процессов в ударной трубе с отражающим соплом для задач планирования эксперимента. Получены оценки рабочего времени, длительности запуска сопла, параметров сверхзвукового потока газа в месте установки модели. Сравнение результатов расчета с измерениями, проведенными на Большой ударной трубе ФТИ им. А.Ф. Иоффе показало применимость данного подхода.
