Natural convection simulation using commercial CFD codes

Natural convection in enclosures is counted as an important phenomenon in many engineering applications. This paper numerically investigates natural convection flow field and heat transfer of different turbulent models. Standard k-e, standard k-w and Shear Stress Transport Model (SST) have been compared with experimental data. The cavity is partially heated. The commercial CFD codes, ANSYS Fluent, are employed. Standard k-w model provided good agreement with the experimental data.
