CFD-Based Multi-Objective Optimization of a Cyclone Separator Using Response Surface Methodology, NSGA-II, and Physical Prototype Validation

Cyclone separators are widely used for gas–solid separation; however, improving separation efficiency generally increases pressure drop, making cyclone design a challenging multi-objective optimization problem. This study aims to optimize a high-efficiency Stairmand cyclone separator by simultaneously maximizing separa...

Performance Comparison of Reverse-Engineered and Newly Designed Impellers in a Centrifugal Pump Operating in Pump and Turbine Modes

This study compares the hydraulic performance of two centrifugal-pump impellers operating in pump and pump-as-turbine (PAT) modes: a reverse-engineered impeller obtained from a commercial pump by 3D scanning and an impeller developed through a preliminary analytical sizing procedure. Both configurations were evaluated...
