Two-dimensional viscous unsteady cavity flow past a wedge in the channel is considered. The statement of the problem is based on the concept of viscous-inviscid interaction of the turbulent viscous wake behind the cavity and unsteady inviscid external cavity flow in which the cavity is closed on the displacement thickness of the viscous cavity wake. The obtained non-linear solution of the problem is linearized to study interaction between conventional surge instability and Struohal instability in the cavity wake.
