Abstract

To study the influence characteristics of downstream wave systems on shock wave/boundary layer interference (SWBLI) in hypersonic inlet, a model was designed which can generate a stable first shock wave by a linear com-pression ramp, and can simulate the change of the downstream wave system by changing the shape of the adjusta-ble compression ramp downstream of the first shock wave. The relation between different shapes of adjustable compression ramp and SWBLI generated by the first shock wave on the upper wall is studied. The simulation re-sults show that the downstream adjustable compression ramp has a significant impact on the SWBLI. Significant SWBLI is observed when the compression ramp is adjusted to be linear or convex. While by adjusting the compres-sion ramp to be concave, the area of the up-stream separation region can be effectively reduced or even eliminated. The results show that the upstream SWBLI can be influenced by the downstream wave system, and can be mini-mized or eliminated by adjusting the wave system.
