Mechanical Design Engineer @Water Works Engineers

AZ, US

Worked on the Design Optimization of Centrifugal Pump Impellers, collaborating with R&D, CFD analysts, manufacturing, and QA teams. Capturedtechnical requirements through design review sessions to enhance efficiency and durability in high-pressure industrial fluid systems.• Designed high-precision 3D CAD models using SolidWorks and performed tolerance stack-up analysis to ensure manufacturability. Reduced impellerweight by 12% while maintaining structural integrity, resulting in lower material cost and improved dynamic balance.• Executed CFD simulations in ANSYS Fluent, optimizing blade geometry for reduced turbulence, minimized cavitation, and enhanced flow uniformity.Achieved a 9.5% increase in hydraulic efficiency and 15% reduction in NPSHr across varying flow conditions.• Collaborated with the test engineering team to validate prototypes via performance testing, counting hydraulic performance curves, vibration testing(per ISO 10816), and long-duration fatigue tests. Simulation results were validated within ±3% of actual test data.• Documented design iterations, FEA/CFD reports, and test outcomes. Integrated feedback from field engineers to finalize production-ready models,resulting in a 20% improvement in MTBF and 25% reduction in maintenance interventions
