完成了超音速燃烧室内非定常准一维流的数值模拟研究。数学模型综合计及了面积变化、物质添加、化学反应、燃烧室壁面散热、壁面摩擦和变比热等各种影响因素，准确地计算出双模态超音速燃烧室的总过程，其主要优点是在未知激波位置情况下，可以分析处理非定常的工作过程。

A quasi one dimensional unsteady numerical analysis of supersonic combustor performance has been conducted.The method can handle internal flow with variable section mass addition,heat release,heat transfer to combustor wall,wall shear and variable specific heat.The theoretical analysis gives a good description of the whole processes taking place in the dual mode supersonic combustor.This method can be used to analyse unsteady processes without assumption of the shock location.
