    Abstract: Experiments are performed on a cylinder with a forward-facing cavity at M = 10 in the FD-14A shock tunnel. The shock-standoff distance and oscillation characteristics are recorded by a high-speed movie, and the dynamic pressure transducer is used to capture the unsteady signal of cavity base. Based on experimental and numerical results, a predicti... Show More
