Article history: The objective of this study is to validate the performance of the current    turbulence model for a single-phase turbulent natural convection, which has been considered an important phenomenon in nuclear safety. As a result, the natural convection problems in the 2D and 3D cavities previously studied are calculated by using the ANSYS Fluent software. The present results show that the current    turbulent model accounting for the buoyancy effect is in good agreement with
