摘要：

As an effective method to extend the stability range of axial compressor, circumferential groove casing treatment has always been the focus of researchers. This paper analyze the stall margin improvement of casing treatment and the flow field in axial compressor. Slot type and circumferential casing treatment are compared to conduct the development situation of optimized casing structure. We introduce a new casing treatment which can extend the stability range and improve efficiency of axial compressor. It turned out that keeping both pressure ratio and efficiency and improving the stall margin of compressor is the most important goal via designing reasonable tip clearance and circumferential groove casing treatment. The design principles can be used as a reference for the industrial sector.
