| Abstract | ||
| Computational results were presented concerning the laminar flow over backward facing step. The solution was accomplished through the rearrangement of the equations of motion into a vorticity transport equation and definition of vorticity equation. Finite differences method was used to solve the differential equations, and also the upwind method with non uniform grid distributions was used to get the converged and stable solution. It was concluded that the laminar reattachment length varies with Reynolds number and boundary layer thickness at the step. The effect Reynolds number, and initial-layer thickness on reattachment length were studied for wide range of Reynolds number | ||
