- •
Turbulent natural convection in 2D/3D rectangular cavities is comparatively investigated.
- •
In 3D models, slenderness ratio of H/W = 1 and H/W = 1 is considered.
- •
Numerical solutions using six turbulence RANS models are obtained.
- •
Heat transfer rate predictions of models are accessed via the mean Nu number over the heated surface area.
- •
Performance of the RANS models are assessed using available experimental and numerical literature.
