1- Re 5000, incommpressible, laminar, steady flow.
2-Non-uniform 151*151 grid such that dx=dy=1/400 near walls.
The CFD setup:
1- Model used: viscous model, laminar.
2- Boundary condition:
The Zero-slip condition at the nonporous walls.
Top wall move with uniform velocity (v= 1 m/s).
Density=1(kg/m^3), and viscosity=(0.0004kg/m-s) with length of 2m, to achieve Re.
3-Solver: steady flow, pressured based and absolute velocity formation.
4- Solution method: Simple scheme, least square cell based discretization, standard for pressure and 2nd order upwind for momentum.
5- Solution control: under relaxation factor,30% for pressure, 70% for momentum, and 100% for both density and body forces.
