To research the evolution of unsteady flow in centrifugal pump under transient condition, and to investigate the mechanism of transient effects by analyzing the unsteady flow in centrifugal, the unsteady flow in a centrifugal pump during rapid starting period was simulated by using of sliding mesh method.The model including whole circulation pipeline and pump was established. The unsteady flow evolution in the pump was analyzed when the impeller started from stationary to maximum speed,and the effects of different pipeline resistance were evaluated.The suitability of numerical method for three dimensional transient flow solving was discussed.The numerical results of transient performances by unsteady flow analysis were similar to the test results.The established methods and results make the basis for the diagnosis and optimization of under flow in the centrifugal pump during transient operation.
