对冷气喷射时激波受到的影响进行了多方案数值研究.在高压级静叶吸力面反射激波生成点前后5个不同位置上采用相同总压及相同温度的冷气喷射,分析了不同位置的冷气喷射对激波强度和方向影响.结果表明:在吸力面激波折射点附近喷射冷气是一种行之有效的控制激波强度的方法.冷气喷射位置位于激波折射点附近时能够对激波的强度产生影响,在接近激波折射点前部位置注入冷气对流动有积极作用,减弱了激波.
The multi-program numerical study on the influence of the shock wave on the air-jet injection was carried out.At the same time the same total pressure and the same temperature were used for air-condition injection at five different positions before and after the generation of reflection shock at the suction side of the high pressure stage, The results show that it is an effective method to control the intensity of the shock wave.It is shown that the location of the cold air jet is close to the refraction point of the shock wave The intensity of the wave has an impact. The injection of cool air near the front of the shock point has a positive effect on the flow and weakens the shock wave.
