摘要: An experimental and numerical study was developed for the unsteady phenomena at off-design conditions of a diffuser pump. Unsteady pressure measurements were made downstream impeller, fluctuations analyzed using ensemble averaging technique as well statistical chaotic time series analysis. The flow classified into five ranges result And two-dimensional vortex method employed to investigate structure due interaction between impeller vanes in pump various
