Abstract

Abstract: The time dependent axisymmetric Navier Stokes equations are solved by a TVD fi-nite volume scheme to simulate viscous flow in an oblique cavity driven by a constant pressure ratio p_e/p_0=0. 318.The numerical results demonstrate the formation and evolution of the complex vortexes structure in detail.self-sustained flow oscillation in the cavity is observed,and the interaction between shear-layer instability and oscillation is discussed.

Key words: TVD schemes, vortices, cavity flow, self oscillation
