Assessment of turbulence model performance adopted near wall treatment for a sharp 90° 3-D turning diffuser

The primary aim of this paper is to assess the performance of k-ε turbulence models by means of adopting various near wall treatments to simulate the flow within a sharp 90° 3-D turning diffuser. The Computational Fluid Dynamics (CFD) results were validated quantitatively and qualitatively with the...
