The predicted performance of a cavitating centrifugal pump, calculated using a method which applies the concept of notional spherical cavities, has been compared with measured performance values. From the close agreement evident in predicting the nett positive suction head at breakdown and the generated head–cavitation zone length curves the method and concept appear suitable for wider engineering application.
The volumetric performance comparisons made use test data on water in the temperature range 2–1433°C.
