A comparison of RANS models used for CFD prediction of turbulent flow and heat transfer in rough and smooth channels

A comparison of RANS models used for CFD prediction of turbulent flow and heat transfer in rough and smooth channels

CFD of convective heat transfer remains a challenge, especially in channels with irregular rough walls due to the complex fluid dynamics over and between these roughness elements. This study investigates the performance of four commonly utilised RANS CFD models, namely Spalart-Allmaras (SA), Realisa...
