Performance Optimization of High Specific Speed Centrifugal Pump Based on Orthogonal Experiment Design Method

A high specific speed centrifugal pump is used in the situation of large flow and low head. Centrifugal pump parameters need to be optimized in order to raise its head and efficiency under off-design conditions. In this study, the orthogonal experiment design method is adopted to optimize the perfor...
