Comparative Study for Different URANS Models for Capturing Flow Separation Inside a Plane Diffuser
A comparative numerical study is performed among different URANS turbulence models investigating the ability of the models to capture the deformation of the boundary layer near the separation zone. The results are validated against previously published numerical works (URANS, LES, DNS) and experimental works. The comparison included grid resolution, the pressure distribution, and the velocity profiles at the inclined wall, then the streamlines plot of each model is used to properly estimate the separation and reattachment points.
