摘要：
A nonlinear method for simulating two-dimensional cavity-flow interaction inhigh velocity flows is suggested. Mathematical model for the dynamics of unsteadycavity boundary and the motion of the outside flow is set up, numerical andexperimental investigations are made for the cavity flow past a two-dimensional bow-shaped body. The results show that because of the nonlinear effect, the trail of thecavity oscillates periodically, while the incipient point of the cavity almostremains fixed. Due to the unsteady oscilation of the cavity trail, the liquidpressure on the solid wall a little downstream of the reattachement point wouldrise sharply.
