质量加入影响固体燃料冲压发动机统一内流场的三维数值计算

3-Dimensional Numerical Calculation of Effect of Mass Addition on Whole Internal Flow Fluid of SFRJ

利用三维隐式有限体积 TVD格式求解 N- S/Euler方程组数值模拟固体燃料冲压发动机 (SFRJ)突扩燃烧室、补燃室和喷管的统一内流场 ,比较研究了从亚音速到跨音速到超音速的整个工作过程中质量加入对流场内部结构的影响 ,并与试验进行对比研究 。

The Whole internal flow fluid of SFRJ including sudden expansion chamber,aftcombustion chamber and nozzle is numerical simulated by 3 dimensional implicit finite volume TVD scheme of N S/Euler aquations in this paper.Effect of mass addition on internal construct of flow fluid of SFRJ is researched in the whole working process from subsonic to supersonic flow.The results have good agreement with experimental data very well.
