The Geometrical Modeling of Meridional Flow Channel for Diffuser of Mixed-flow Pumps

建立了空间导流器轴面流道的几何模型 ,并对其特点进行了分析 ,给出了求解过流断面面积的方法 ,并列举了计算实例。

The shape of meridional flow channel for diffuser of mixed-folw pumps is given, the geometrical model of different section of the diffuser is built, and the characteristics of the model is analyzed. A mathematical model describing the meridional flow channel geometry and an iterative method for calculating the area of through-flow are proposed. Finally, an example is worked out.
