The primary aim of these investigations was to explore the characteristics of flow and heat transfer under varying Rayleigh numbers and aspect ratios. The results obtained through Computational Fluid Dynamics (CFD) simulations, presented graphically in the form of heat flow and stream functions, reveal that the nature of heat transfer is influenced by both the Rayleigh number and aspect ratio. Moreover, the study validates the strong dependence of the Nusselt number on the Rayleigh number, aspect ratio, and enclosure parameters. The CFD simulations effectively capture the boundary conditions of the natural convection problems under consideration.Solutions are derived for a range of Rayleigh numbers, maintaining a constant Prandtl number (Pr = 0.70) at an aspect ratio of 1. The Pressure-Velocity Coupling Method, coupled with the Non-Iterative Time Advancement (NITA) scheme, is employed to effectively solve the problem. The distribution of temperature and stream function is analysed as a function of thermal and geometrical output parameters for the specific problem at hand. The investigation involves a two-stage approach to discern variations in results stemming from different computational approaches.
