RBCC引射模态准一维性能分析模型

基于准一维非稳态流动方程建立了RBCC引射模态性能分析模型，充分考虑壁面摩擦、有限速率化学反应和质量添加等因素。模型采用MacCormack格式求解，很好的解决了计算引射比、考虑环境压强等问题。与实验结果的对比表明，本模型计算结果的相对误差为5％～9％，发动机内的压强分布与实验结果基本一致，本模型可用于RBCC引射模态性能分析。

Quasi-1D analysis model of rocket ejector mode

Performance Analysis Model of Rocket Ejector Mode was established, based on quasi-1D transient flow equations. Factors such as skin friction, finite rate chemical reaction and mass injection were taken into account. A Mac- Cormack scheme was adopted for solving the equations, which obtains by-pass ratio correctly and well considers the ambient pressure. Compared with experimental results, the relative errors are about 5% - 9% and internal pressure distributions are basically consistent with experiment results, showing that the model is applicable for Rocket Ejector performance analysis.
