shock-wave reflection

There are four major problems for transonic wind tunnels to generate transonic airflow: Solving the air-logged condition; Generating the equably low supersonic airflow; Reducing or eliminating the wall interference of subsonic airflow; Reducing or eliminating the influence of the shock waves' reflection.

跨声速风洞产生跨声速气流主要有四个问题：解决风洞的堵塞现象；产生均匀的低超音速流动；减少或消除亚音速洞壁干扰；减少或消除激波反射的影响。
