扰动波对轴流压气机旋转失速的影响

EFFECTS OF DISTURBANCE WAVES ON ROTATING STALL STABILITY OF AXIAL COMPRESSOR

提出了考虑轴流压气机进出口气流角和非定常损失变化的二维旋转失速稳定性模型，进行了数值分析和讨论。计算结果表明压气机前方的扰动波对压气机旋转失速稳定性有一定的影响，压气机本身的结构形式以及压气机上。

A 2-D rotating stall stability model considering the inlet and outlet flow angles and unsteady loss of axial flow compressor was proposed,for which numerical analysis has been conducted.The calculated results show that the disturbance waves at the upstream of compressor have influence on the rotating stall stability.The configuration of the compressor produces a strong impact on the propagation speed of the distrubance waves.
