摘要: 以叶轮机械内部流动研究方法为线索,分别从理论分析、试验测试和数值计算三个方面对国内外叶轮机械内部流动的研究进展和现状进行综述。首先概述叶轮机械内部流动损失的分类、定义和研究现状。然后分别从分离流动理论、涡动力学和叶轮机械流型三个层次介绍叶轮机械内部流动理论的发展;从平面叶栅、环形叶栅、动态试验和试验技术等方面回顾叶轮机械试验研究进展;从控制方程、数值方法、网格生成等方面综述叶轮机械数值计算研究方法、研究内容及成果等,并概括改善叶轮机械气动性能的方法和现状。最后对叶轮机械内部流动研究进行展望。结果表明,叶轮机械内部流动研究取得了巨大进展,有些研究成果已经应用到了设计工作中,但仍需对叶轮机械内部流动进行更深入的研究。

Abstract: The inland and overseas advance and current status of the investigation into internal flow of turbomachinery are reviewed in terms of theoretical analysis, experiments and numerical simulation respectively. The classification, definition and investigation status of internal flow losses of turbomachinery are outlined at first. The theoretical development of internal flow of turbomachinery is then summarized in terms of separation theory, vortex dynamics and flow pattern. The advance of experimental investigations of turbomachinery is reviewed in terms of linear cascade, annular cascade, unsteady experiment and measurement techniques. The methodology, content and achievement of numerical simulation are summarized in terms of govern equation, numerical technique and grid creation. The ap-proaches to improve the aerodynamic performance of turbo-machinery are reviewed and the perspective of this research field is conducted finally. The results show that the investigation into the internal flow of turbomachinery has achieved great improve-ment and many achievements have been implemented in the de-sign, and more in-deep study is still needed in this field.
