Study on improvement of the compressor anti-swirl distortion capacity with bowed stator

  • 摘要: 为降低旋流畸变对轴流压气机性能和稳定性的影响,对双级低速轴流压气机的第1级静子进行了3种不同正弯角的弓形叶片设计.采用整环三维定常计算方法,研究了对涡旋流下压气机的性能和稳定性.结果表明:静子采用合理的正弯曲设计能够提高压气机抗对涡旋流的能力.正弯曲弓形静子能够降低端壁区域的负荷,抑制各排叶片叶根区域吸力面附面层分离的形成以减小损失、提高效率和总压比.静叶弯角为10°时峰值效率增加1.5%,失速边界点流量减小6.95%.流量为18.5kg/s时,效率、总压比分别增加1.7%和0.03%.当弯角过大时,叶中区域负荷上升且摩擦损失增大,反而不利于效率和总压比的提升.
