全可控涡分布对离心压缩机三元叶片性能影响研究

摘要

针对全可控涡三元叶轮设计方法中的全可控涡给定方法，给出2种不同的全可控涡分布给定方法，根据流线曲率法反命题编写三元叶片设计程序，并结合具体案例，分析比较不同全可控涡分布对离心压缩机三元叶片性能的影响。%Based on Three-Dimensional Flow theory, the streamline curvature method is analyzed and a design program about the compressor impeller is coded.The angular momentum, an input parameter of the program , is considered as a control parame-ter.It effects on the convergence of the program , the flow field, the blade shape and the compressor performance are analyzed in detail.
