摘要: Experimental and computational study was developed for unsteady hydrodynamic forces on a diffuser pump impeller excited by the interaction between vaned with same number of vanes as impeller. Unsteady flow calculations are made using commercially available CFD software, CFX-TASCflow, well two-dimensional vortex method. Calculated pressure fluid show good agreement measured ones. It has been demonstrated that smaller compared other combinations vane numbers. However, fluctuations found to be greater than cases.
