ABSTRACT

The review begins by introducing the importance of numerical analysis in assessing the performance of solar water heaters. It emphasizes the need for accurate predictions of system efficiency, energy output, and thermal behaviour to guide design improvements and inform decision-making.  The paper then presents an overview of the various numerical analysis techniques employed in studying solar water heaters. These techniques include computational fluid dynamics (CFD), finite element analysis (FEA), and thermal modeling, among others. Each method is discussed in terms of its strengths, limitations, and applicability to different aspects of solar water heater performance analysis. The review explores the parameters considered in numerical simulations, such as solar radiation, fluid flow, heat transfer, and system components. It examines the influence of these parameters on system performance and provides insights into optimizing their values for enhanced efficiency. The review also addresses the challenges and limitations associated with numerical analysis of solar water heaters, including modeling assumptions, computational complexities, and validation of results. Recommendations for future research directions and advancements in modeling techniques are presented.
