A 3D numerical simulation is also conducted and the computational results are validated with the experimental ones. The flow rates examined correspond to the laminar, transitional and beginning of turbulent flow regime. The numerical results concerning wall shear stress profiles behind the step and the position of the reattachment point are in good agreement with the experimental data.
