摘要： 针对转子失速时叶顶的具体流动情况，基于抽吸叶顶堵塞区低速流体的目的，设计了四种新的自循环机匣处理方案，探究其扩稳机理与常规自循环机匣处理的作用差异。数值计算选用Numeca Fine软件包的Euranus求解器，计算结果表明，通过抽吸叶顶堵塞区低速流体设计的自循环机匣处理结构，其达到的扩稳效果高于常规的自循环机匣处理。在优化设计中，当轴向引气位置位于转子叶顶堵塞区核心附近时，达到的扩稳效果最好，最大综合裕度改进量能达到15.00%。此外，本文还分析了自循环机匣处理后转子叶顶流场的差异，得出自循环机匣处理的扩稳机理在于把造成叶顶区堵塞流动的低速气流吸走，抑制了叶顶泄漏流动，改善了叶顶区的流动状况，以此来扩大转子的稳定工作范围。

Abstract: For the specific flow condition of the tip of the rotor during stalling, based on the purpose of pumping the low velocity fluid in the blockage area of the tip, four sets of self-circulating casing treatment schemes are designed to explore the difference between the expansion mechanism and the conventional self-circulation casing treatment. The Euranus solver of the Numeca Fine software package is used in the numerical calculation. The calculation results show that the self-circulating casing treatment structure designed by pumping the low-speed fluid in the plugging area of the tip is more stable than the conventional self-circulating casing treatment. In the optimized design, when the axial bleed air position is located at the core of the rotor tip blockage area, the achieved stabilization effect is best, and the maximum comprehensive margin improvement can reach 15.00%. In addition, the paper also analyzes the difference of the top flow field after the self-circulating casing treatment, and concludes that the expansion mechanism of the self-circulating casing treatment is to suck away the low-speed airflow causing the blockage flow in the tip area, suppress the leakage flow at the tip, and improve the flow condition in the tip area， which is used to expand the stable working range of the rotor.
