The twin vortex at the tip clearance of hub side and the asymmetric recirculation at wall of inlet duct are also observed. 4 The mass-weighted average of flow parameter at inlet and outlet of every passage of impeller changes with different positions. In addition to the above, with the unsteady method, the head rise, shaft power and efficiency have been predicted well.

再次，采用整机非定常计算准确预测了三种工况下部分流泵的扬程、轴功率和效率；发现了叶轮进出口质量加权平均的速度、压力、动量矩的宏观不变特性；蜗壳内流动的非定常性对部分流泵的外特性有重要的影响。
