摘要：

In this study, a feedback mechanism for supersonic deep-cavity flows is modeled. The model is developed on the basis of previous flow visualization results. In this model, two pressure waves play an important role in the feedback mechanism; one wave is generated at the trailing edge of the cavity owing to the motion of the shear layer, and the other wave is generated as a result of the third reflection of the former wave at the cavity bottom. The constants in the model are determined using the flow visualization results. The frequencies calculated in the model agree well with the dominant frequencies observed in experiments; in particular, the feedback mechanism responsible for deep-cavity-induced pressure oscillation is successfully clarified.
