一种新的中间流线绘型方法

A new way of drawing middle streamline

以叶轮设计原理为基础,在确定出离心叶轮全部几何参数之后,以计算方法划分叶轮轴面流道内的中间流线。实际效果表明,该方法可靠,能缩短设计周期,提高设计精度。

Based on principles on centrifugal impellers design, the authors of this paper calculated middle streamline in the flow passage in an impeller, after determining geometric parameters with advanced method. The actual results indicate that the new method presented here will cut down design periods and improve design accuracy.
