КОМБИНИРОВАННЫЙ МЕТОД РАСЧЁТА БЕЗУДАРНОГО СИЛЬНОГО СЖАТИЯ ОДНОМЕРНЫХ СЛОЁВ ГАЗА В КОНФИГУРАЦИИ Р. МИЗЕСА

Abstract

В статье изложены результаты численного исследования задачи безударного сильного сжатия одномерных слоёв газа в конфигурации Р. Мизеса в прямом направлении изменения времени. Приводится комбинированный алгоритм расчёта течения, использующий конечно-разностный метод «Ромб» и особый способ аппроксимации движения правой границы, обеспечивающий более точное описание течения в окрестности слабого разрыва. Приведены численные расчёты сжатия одномерных слоёв с различной симметрией до достаточно больших значений плотности. Полученные результаты расчётов сравниваются в том числе и с известным точным решением.
