为了对进气道内斜激波/边界层干扰进行控制,采用RSM模型,以二维平板/楔结构为基础,研究了斜激波冲击平板诱导边界层分离现象,探讨了吹除状态下流场波系结构和壁面参数分布,分析了吹除位置和总压对分离区及流场的影响.研究表明加入吹除控制之后,流场参数得到了有效改善,吹除喷嘴靠近分离区,吹除效果更好.吹除总压并不是越高吹除效果就越好,存在一个最佳吹除压力,该压力就是使吹除喷嘴出口气流达到近似音速,这一结论如进一步得到实验证实,对实际工程具有指导意义.
In order to control the in-channel diagonal shock / boundary layer disturbance, the RSM model was used to study the separation of the boundary layer induced by the slant shock plate based on the two-dimensional plate / wedge structure. Wave structure and wall parameter distribution were analyzed.The influence of blowing position and total pressure on the separation zone and flow field was analyzed.The results showed that the flow field parameters were effectively improved after blowing control was removed.The blowing nozzle near the separation zone and blowing The effect is better.Blow-off the total pressure is not the higher the blow-off effect, the better, there is an optimum blow-off pressure, the pressure is to make the blow-off nozzle outlet airflow to approximate the speed of sound, this conclusion as further confirmed by experiments, The actual project is instructive.
