摘要(Abstract):

利用CFD软件分别对前向和后向叶轮旋涡风机的单个叶道进行流场分析,得到前向和后向叶轮单个叶道的压力性能差异。然后进行试验研究,得到前向和后向叶轮整体的压力性能差异。
Use CFD software,the area of flow channel for forward skewed and backward skewed impeller was analyzed,and the differences in the performance of pressure between them was got.then the whole performance differences between them was got by test.
