Mechanism of the rotor−stator interaction in a centrifugal pump with guided vanes based on dynamic mode decomposition

In this paper, the mechanism of the rotor–stator interaction in a centrifugal pump with guide vanes is studied numerically and theoretically. The dynamic mode decomposition method is employed to decouple and reconstruct the unsteady flow. A diametrical mode theory suitable for centrifugal pumps with...
