摘要
为了应对高效发电趋势,提高汽轮机和燃气轮机的效率,必须对动叶流场气动性能进行准确的测量和分析。高频响气动探针可以有效的对涡轮机械中三维非定常流场进行时间分辨测量。而探针的研制主要涉及探头形状、大小,气动腔动态特性,标定以及数据后处理。文中对这几个方面的国内外研究现状和发展趋势进行了详细阐述,总结了它们各自的特点、适用范围和局限性,并指出了今后的研究方向以及难点所在,为相关科研人员进一步开展探针理论分析、数值模拟研究和应用设计提供参考。
In order to improve the efficiency of steam turbine and gas turbine,it is necessary to measure accurately the aerodynamic performance of the flow field,expecially the unsteady flow field.The high frequency response aerodynamic probe can effectively measure the three-dimensional unsteady flow field in turbomachinery.The development of high frequency response probe mainly involves the shape and size of probe,dynamic characteristics of pneumatic cavity,calibration and data post-processing.In this paper,the research status and development trend of the probe in these aspects were reviewed.The respective characteristics,scope of application and limitations of high frequency response probes were summarized,and the development directions and difficulties in the future were pointed out,which provides reference for relevant researchers to further carry out theoretical analysis,numerical research and application design.
