摘要： 本文提出了一种产生具有空间扭曲叶片离心叶轮流道附体坐标系的新方法。这种坐标系通过依次求解若干个二维椭圆型偏微分方程而生成,与直接求解三个3-D椭圆型偏微分方程产生附体坐标系的方法相比,本方法可节省大量计算时间和计算机内存。以某离心压缩机三元叶轮为例给出了具体计算结果。
Abstract: A new method to generate 3-D body-fitted coordinate system for the channels of centrifugal impellers was described. The coordinate system is generated by solving a number of 2-D elliptical partial differential equations. Comparing with the method directly solving three 3-D elliptical partial differential equations for body-fitted coordinate systems, this method can save much computer time and storage. An example of coordinate generation for a centrifugal compressor impeller was given.
