An experimental study was conducted to investigate the transonic convex-corner flows with and without the presence of an upstream cavity. Measurements were made to investigate the geometric effect and the spacing of a cavity on attached and separated convex-corner flows. The upstream expansion and downstream initial recompression are strongly affected by the upstream cavity, which includes the delay on the transition of subsonic and transonic expansion flows, the initial boundary-layer separation, the characteristics of separated flow, and the intensity of surface pressure fluctuations.
