Flows in the impeller pump are typical among engineering fluid flows. In this chapter, we select a low-specific-speed centrifugal pump as an example to demonstrate research methods commonly used in this aspect. This pump is equipped with long and short blades. Both the pump performance and inner flow characteristics at various flow rates are studied. The design of the pump impeller is optimized, which is expected to be validated through the proof extracted from the flow field. Unsteady numerical simulation is conducted to disclose inner flow patterns associated with the modified design. Meanwhile, an assessment of the hydraulic forces exerted on the pump components is implemented based on numerical results.
