Abstract

This study presents the results of the theoretical model 10 predict the centrifugal pump performance when its impeller is equipped with splitters. The proposed methodology accounts for the constructional differences of the pump equipped with splitter blades as compared with the conventional pump. For flow through axial blade rings, there is a distinct influence of the solidity on the outflow angle from the blades. This analogy is used for the derivation of a slip factor for impellers with splitters. A loss analysis procedure has been presented to predict the performance of centrifugal pumps. The result is compared with available experimental results. The predicted values of head over the operating range of flow rate of the pump have been found to be in reasonable agreement with the measurements.
