用单斜丝详细测量了单转子压气机设计状态和近失速状态转子出口的三维素流流场。结果表明，设计状态叶尖泄漏涡和端壁附面层的掺混是造成尖部流动损失、气流阻塞和亲流脉动的主要原因。近失速状态流动三维性和非定常性较强；尖部吸力面角区轴向速度最低、相对动能损失最大；吸力面附面层径向潜移、叶尖吸力面角区低能团周向潜移及其输运的低能物质在尖部通道中部与叶尖泄漏流、泄漏涡、刮削涡发生掺混，造成尖部大范围的高损失区；根部和尖部吸力面阻面层局部发生分离。
The design of the single-rotor compressor and the three-dimensional flow field of the rotor at the exit of the near-stall state were measured in detail with single-skew wire. The results show that the mixing of the tip leakage vortex and the end wall at the designed state is the main cause of tip flow loss, air flow obstruction and in-stream pulsation. Nearly stalling state flow has strong three-dimensional and unsteady flow; the tip suction surface has the lowest axial velocity and the largest loss of relative kinetic energy; the radial displacement of the suction surface, The transport of low-energy material in the tip of the central channel and tip leakage flow, leakage vortex, scraping eddy vortex mixing, resulting in a wide range of high-loss area; root and tip suction surface layer of local separation.
