The hydrodynamic design optimization and performance analysis of a mixed-flow waterjet pump have been achieved using the validated commercial computational fluid dynamics (CFD) code. The detailed flow field in the waterjet pump is investigated by the CFD code adopted in the present study. Predicted characteristic curves, including the cavitation performance, agree very well with the test data for a designed mixed-flow waterjet pump over the entire operating conditions. A hydraulically detailed performance analysis with a net positive suction head can be used efficiently as a tool for the practical design optimization and assist in the understanding of the operational characteristics of general purpose mixed-flow pumps.
