Webb11 apr. 2024 · In light buffeting state, the small-amplitude shock oscillation is insufficient to trigger separated flow, which belongs to the second mode of boundary layer separation. Influenced by the incoming flow, the shock wave oscillates at the moment a, and then the reattachment point moves to the right, and the wake has a large-scale vortex structure.
