离心压缩机蜗壳型线的一种二维逆命题计算方法

本文提出一个蜗壳型线的二维逆命题计算方法。该方法考虑了蜗壳进口流动参数沿圆周方向分布不均匀和蜗壳周向平面内损失分布的影响；改进蜗壳与叶轮或扩压器之间的匹配关系，改善离心压缩机和风机的性能，提高蜗壳的设计质量。

A Two-Dimensional Inverse Design Methodfor the Scroll Casing of a Centrifugal Compresaor

In this paper,a two-dimensional inverse method is presented to design the scroll casing of a cen-trifugal compressor. The non-axisymetric inlet flow conditions on the scroll base circle and the flowlosaes in the scroll are taken into account by means of this method so that the design of the scroil andthe performance of the centrifugal compressor can be improved.
