Abstract

The up-to-date methods of computational fluid dynamics (CFD) were employed to study the effect of mass flux ratio above the submerged part of a solid rocket engine nozzle with a contoured inlet on the discharge coefficient. The results are given in correlation with the inlet geometry and nozzle submergence.

带有入口轮廓的喷嘴浸没部分上方的质量通量比对排放系数的影响

摘要

采用了最新的计算流体动力学方法（CFD），研究了具有等高线形进气口的固体火箭发动机喷嘴浸没部分上方的质量通量比对排放系数的影响。给出的结果与入口的几何形状和喷嘴的浸没有关。
