Centrifugal pump design has reached the stage where to improve efficiency much research is necessary for limited returns, whereas the application of model techniques to the design of pumping systems in general and pump intakes in particular can yield immediate and manifold savings.
Test rig requirements and test techniques applicable to pump intake models are described, and limitations regarding model size and flow velocities are discussed in relation to scale effects.
Cumulative results to date on typical intakes for large circulating water pumps are summarized and design trends are assessed.
