An integrated framework for PAT micro-hydropower: experimental characterization, NSGA-II impeller-volute optimization, and resin MSLA manufacturing

Pump-as-Turbine (PAT) technology offers a cost-effective route for micro-hydropower in off-grid Andean communities, but adoption remains limited: manufacturers rarely publish turbine-mode curves, and the available geometries were originally designed for pump operation. This paper presents a framework that combines base...

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...

Hydraulic Loss–Based Genetic Optimization and CFD Assessment of a Reversible Centrifugal-Pump Impeller Operating in Pump and Turbine Modes

This study presents a computationally inexpensive preliminary sizing and parametric-design procedure for a centrifugal-pump impeller intended for exploratory operation in pump and turbine modes. A hydraulic loss model was coupled with a real-valued genetic algorithm to screen a restricted design space without embedding...
