Reducing engine emissions through increased efficiency of engine is crucial to lessen the adverse effects of ongoing global warming. An effective design of cooling systems has a proven effect on the enhancement of cooling systems. Industrial perspectives have shifted from traditional product development methodologies to rapid prototyping approaches as a result of rapid prototyping and manufacturing techniques. The aim of this study is to design, analyze and optimize the radiator water pump impeller manufactured through fused deposition modelling, by using ABS. Several geometries of different designs of automobile cooling system water pump impellers were designed and analyzed using solidworks and ANSYS. One conventional and two optimized designs were finalized based on cost, weight, functionality, and manufacturability. The experimental investigation was also carried out for the validation of results at different RPMs. Optimized model C had an 80% improved flow rate model B had a 50% improved flowrate as compared to the conventional design.
