Turbulent natural convection (Ra = 1.58 center dot 10(9)) in a confined 3D square cavity with two differentially heated side walls are simulated numerically using the in-house EDF code (Code_Saturne) based on the unstructured finite volume solver. The objective of the present work is to investigate the performance of the low-Reynolds-number models known by their good suitability for the near-wall treatment. The low-Reynolds-number models, shear stress transport (SST) k-omega. model, phi-f model which is a developed version of the original (upsilon) over bar (2) - f model, and the LES (large-eddy simulation) technique are used, and the results of their using are compared with the experimental benchmark data. The numerical results show quantitative and qualitative agreements. In general, the SST k-omega model gives good predictions for the temperature profiles, and the phi-f model is more accurate for the velocity profile prediction. This is mainly due to the good resolution of the turbulence properties in the near-wall region and to the ability to mimic the physical flow features in this type of geometries.
