abstract

Turbulent flow in a rectangular duct with a plate blockage attached to the lower wall was numerically solved. The computational models used were Large Eddy Simulation (LES), 2D and 3D, steady and unsteady Reynolds-averaged Navier-Stokes (2D-SRANS and 3D-URANS). The fluid was air in all computations, and the Reynolds number (Re) was 5000 and 30,000. The predictions of LES were in several ways closer to the experimental data. For the two values of Re considered in this study, the LES over-predicted the location of maximum Nusselt number (Nu) by 24.1–24.9%, while the 3D-URANS under-predicted it by 23.7–36.8%. The best prediction for the value of maximum Nu was made by LES for Re = 5000, which was 9.3% higher than the experimental value. The LES under-predicted the maximum Nu by 24.1% for Re = 30,000. In the given range of Re, the under-predictions of 2D-SRANS and 3D-URANS for the value of maximum Nu were, respectively, 15.1–16.5% and 25.9–30.1%. As to the location of flow reattachment, the best value was predicted by the 2D-SRANS, while those of LES and 3D-URANS were close.
