Study on Rotating Stall Mechanism of Mine Contra-rotating Main Fan Under Inlet Distortion Condition

  • 摘要: 为了揭示畸变进气条件下压入式矿用对旋风机的旋转失速机理,基于分离涡模拟方法与节流阀模型,对旋风机内部的非定常流动开展了数值模拟与分析。结果表明:对旋风机两级叶轮内的失速起始扰动均为“突发型”,均首先发生于叶顶区域,但前级叶轮较后级叶轮更早地进入旋转失速状态。后级叶轮叶根区域也同样出现了扰动,但该处扰动是独立产生和发展的。另外,两级叶轮内失速团的传播均是通过相邻叶片通道流入的反流与本叶片通道流出的反流所引起的失速团扰动强度沿叶轮周向的变化来实现的,前级叶轮内失速起始扰动与失速团的传播速度分别为叶轮转速的60.9%和35%,后级叶轮内二者的传播速度分别为叶轮转速的55%和46%。
