Analysis of Unsteady Flow Structures in a Centrifugal Impeller Using Proper Orthogonal Decomposition

The occurrence and development of the dominant unsteady flow structures in a vanless centrifugal pump impeller are revealed by the proper orthogonal decomposition (POD) method. The pressure and velocity data of four radial surfaces is selected as the variables of decomposition. The results show that...
