Cavity flows: change of regime in the ratio between the pressure and kinetic energy flows across the cavity mouth.

View File

The incompressible flow in a rectangular cavity located along one of the wall of a plane channel is studied. The focus is put on the flow in the cavity and on the energy dynamics, in particular on the pressure and kinetic energy exchange across the interface surface between the cavity and the channel. Moreover, using the incompressible formulation of fluid equations, we look for observable properties that can be associated to acoustic emission which is normally observed in this kind of flow beyond a critical value of Reynolds number.
