摘　　要：针对单圆弧叶片流道内容易产生脱流及圆柱形叶片包角不能调整而增加水力损失这一问题,提出了拼接变角螺旋线和对数螺旋线进行圆柱形叶片设计的方法,用Pro/E完成了这种叶轮的建模,并用fluent流体分析软件对叶轮进行了模拟计算。结果表明这种复合型线的叶片可以改善叶轮的内部流动。In order to solve the problem of flow separation along single arc blade surface and the wrapping angle can not be changed which increase the hydraulic loss,this paper presented a method to form contour of cylindrical blade by employing variable angle spiral and logarithmic spiral,and the three dimensional model of the impeller was established with Pro/E. Finally,tile FLUENT software was applied to simulating two types of the impeller. The simulation results show this contour can improve the internal flow characteristics of impeller.
