On the structure of separated viscous flows
Abstract
This paper considers the steady flow in a square cavity where the flow is driven by the uniform translation of a moving boundary at the top. Numerical solutions of the full Navier-Stokes equations are obtained for Reynolds numbers from 400 to 3000 using an alternating direction implicit (ADI) method. The numerical results agree with the experimental observations of other investigators as well as with the analytical solutions of two linear limiting cases. These results indicate that the high Reynolds-number steady-flow consists of an inviscid vortex core with the viscous effects confined to thin shear layers near the boundaries.
