Numerical Solution of Navier-Stokes Equations for Separating and Reattaching Flow over a Double Steps Ezpansion and Contraction

摘要：

This paper shows a numerical solution for Navier-Stokes equations for well known flow phenomenon; the flow separation and the boundary layer reattaching of a double steps expansion and contraction channel. This paper discusses research variables that directly impact the ability to obtain non-circulating flow and techniques to reduce flow separation. This study shows that the separation and the circulation of the flow can be minimized and that is by injecting cross flow (90-degrees) with a magnitude of 0.2 of the inlet velocity.
