Steady Laminar Backwards Facing Step

Hello!
I am writing code to solve 2D Steady Laminar Backwards Facing Step problem for Reynolds number up to 400 through finite differences with dimensionless 2D Navier-Stokes equations. The boundary conditions are the following: Inlet: Parabolic profile for u, v=0, pressure calculated by the pseudo-compressibility continuity equation. Walls: u=v=0, pressure calculated by the pseudo-compressibility continuity equation. Outlet: θu/θx=0, θv/θx=0, p=0. I am running the code but after the step the flow has an upwards direction where it would be expected going downwards with recirculation area. Any help? Thank you very much. |
