摘要: 对有分流叶片的径流式压气机叶轮作叶片面的上下游延伸流面,在接长了的叶轮叶片通道内,用准正交面法求解三元流场。本方法可应用于这类叶轮存在进口预旋情况下的流场分析,也可应用于变工况流场分析。

Abstract: For a radial flow compupressor impeller with Spitter blades. The impeller blade passage was Prolonged by extending the stream surface of up and down stream and then making a long then passage of impeller blade. In this prolonged passage, three dimennsional Flow field was Solved by the Quasi-Orthogonal Surface. This method may be used for analyses of the flow field in this Kind of impeller with Prerotary flow and it may be used for analyses of varied working condition.
