Functional Modelling of Pump Volute Geometry

The task of hydraulic design is usually undertaken using traditional techniques, coupled with many simplifying assumptions. This can lead to long design lead-times and under-utilisation of performance potential. New computational approaches are now required. In this resolve, some considerations of linking intelligent computer technology with fundamental aspects of hydraulic design, in particular pump volute geometry, are discussed. The paper firstly reviews volute flowfield measurements and the effects of geometry, and goes on to discuss some recent experiences in developing an experimental system to provide a functional modelling facility.
