mechanical systems, including energy generation, water treatment, and automotive engine cooling systems. The impeller plays a crucial role in determining the overall performance of a centrifugal pump, particularly through the geometry of its blades. One specific feature—the trailing edge, which is the rear edge of the blade—is often overlooked in pump design. However, this component significantly affects the internal flow characteristics, pressure distribution, and energy losses within the pump. The necessity of this research arises from the ongoing demand to optimize fluid machinery for higher efficiency, reduced operational costs, and lower environmental impact. Traditional designs, while effective, are not always optimized for modern requirements that demand energy-saving and compact systems. Advances in Computational Fluid Dynamics (CFD) have made it possible to explore alternative impeller designs in a cost-effective, precise, and non-invasive manner. This study is particularly important because it: - Addresses an under-researched area of impeller blade design - Applies advanced CFD tools to simulate real-life fluid dynamics without the need for expensive prototypes -Offers practical implications for improving pump design in various sectors, especially those requiring compact and efficient fluid transport systems - Contributes to academic literature and industrial best practices by identifying optimal trailing edge shapes that enhance pump performance This study is particularly important because it: • Addresses an under-researched area of impeller blade design. • Applies advanced CFD tools to simulate real-life fluid dynamics without the need for expensive prototypes. • Offers practical implications for improving pump design in various sectors, especially those requiring compact and efficient fluid transport systems. • Contributes to academic literature and industrial best practices by identifying optimal trailing edge shapes that enhance pump performance.
