Study on the mechanism of stability improvement of the self-recirculating casing treatment in a counter-rotating compressor

  • 摘要: 为拓宽自循环机匣处理的适用范围,以对转压气机为研究对象,采用数值方法研究了自循环机匣处理的扩稳机理和轴向喷气位置对其扩稳能力的影响,详细分析了自循环机匣处理前后对转压气机的总体特性和转子叶尖流场的变化。结果表明:对最先失速的转子配置自循环机匣处理可以获得可观的裕度改善,但轴向喷气位置对扩稳效果和压气机的气动性能均有显著影响;轴向喷气位置不宜距离叶片前缘太近,喷气位置距离叶片前缘40%轴向弦长时失速裕度提高了7.73%且峰值效率损失最小。自循环机匣处理通过降低叶尖负荷和减弱叶顶二次泄漏流强度以及抑制叶顶泄漏流与主流相互掺混来延迟失速发生。通过自循环机匣处理可以改变对转压气机的最先失速级,但不改变失速起始类型。
