This paper presents a meticulous Computational Fluid Dynamics (CFD) investigation focused on unravelling the complexities of natural convection within a square cavity. Utilizing Fluent software, our study delves into the intricate interplay of fluid flow and heat transfer phenomena under varying conditions. The primary objectives encompass a parametric exploration involving the systematic variation of critical factors such as the Rayleigh number and temperature differentials. To establish the reliability of our simulations, a comprehensive validation process is undertaken, comparing the numerical results with experimental data drawn from benchmark studies on natural convection in enclosed spaces. The agreement between our findings and established experimental outcomes reinforces the accuracy and credibility of our computational model. The numerical simulations yield detailed insights into flow structures, temperature distributions, and heat transfer characteristics within the square cavity. Through a series of systematic parametric variations, we discern patterns, dependencies, and optimal conditions governing the natural convection phenomena. The results are discussed in the context of existing theories, and the implications for practical applications, particularly in the realms of thermal management systems and building design, are elucidated. This study not only contributes to a comprehensive analysis of free convection in a square cavity but also serves as a benchmark for future research endeavours in the field. The systematic parametric approach employed in this investigation enhances the depth of understanding and provides valuable insights into the intricate dynamics of natural convection within enclosed geometries
