Design, optimization, and testing of a high-speed centrifugal pump for motorsport application

Centrifugal pumps are designed to have their BEP (Best Efficiency Point) for a given flow rate, hydraulic head, and speed. In the design phase, those parameters are combined into a dimensionless specific speed used to define geometry of the pump. In this paper, a downsized centrifugal pump has been...
