本文采用MacCormack预校二步差分格式对一维非定常两相流动喷管进行了数值求解,得到了固体火箭发动机压力建立过程中气相和凝相颗粒参数的变化规律.
In this paper, one-dimensional unsteady two-phase flow nozzle is numerically solved by MacCormack two-step difference scheme. The variation law of gas phase and coagulation particle parameters in the process of solid rocket motor pressure build-up is obtained.
