摘要
对固体火箭发动机主动引射高空模拟试车系统中的扩压器部分进行研究。采用数值方法对扩压器流场进行模拟求解,比较含与不含粒子对扩压器流场的影响。数值计算结果与试验结果符合性较好,表明用数值模拟方法是扩压器流场的计算的一种有效研究手段。
The article studys the diffuser in the active injector altitude simulated test system of solid rocket engine. It numerically solves the flow field of the diffuser.It compares with the effection on the flow field of the diffuser which contain with particles and no particles. The calculated result agrees well with the test result. It shows that the numerical methods can be used for the study of the diffuser.
