摘　　要：为了分析离心泵内三维不可压缩流体相关特性,以便更好地利用其结果对离心泵进行设计与修正。运用CFDesign流体分析软件,对离心泵内三维不可压缩斋流流动进行了数值模拟。分析了离心泵吸入室、涡室内流体不同截面处的压力及速度特性;并得到了泵的流量及扬程值其结果与实验值达到了很好的吻合。To get the fluid character in centrifugal pump which can be used in designing pump, fluid in centrifugal pump was analysed.The CFDesign fluid analysis software was applied to simulate the three dimensional impressible turbulent flow field in centrifugal pump in this paper.Analysing the pressure and speed character of different cross-section in pump suction and pump volute.The flow and head of pump were gotten which met the experiment value satisfactorily.
