用插值函数绘制离心泵叶片流线展开图

Drawing Spread Picture of Centrifugal Pump Blade Streamline Using Interpolating Function

提出了一种用n次插值函数绘制离心泵叶片流线展开图的方法。利用该方法绘制叶片流线展开图,可通过选择不同的插值节点,方便地控制或改变叶片流线展开图形,以满足不同的设计要求。

Presents a method of drawing the spread picture of centrifugal pump blade streamline by nth order interpolating function. With the method, it is convenient to control or change the blade streamline spread picture by selecting different interpolation nodes, so as to meet different design requirements.
