| 摘 要： | 激波/漏流涡干扰系旋转运动与突然的逆压力梯度的强相互作用，引起各自形态和强度发生变化。涡破裂对风扇/压气机效率和稳定性十分不利。本文探讨了激波/漏流涡干扰的物理模型，通过求解涡核运动方程，分析了涡核特征参数对涡破裂的影响，为控制涡破裂提供了根据。

| Abstract: | A strong interaction between shock wave and leakage vortex,induced by an intensive inter-impact of rotating motion on abrupt anti-pressure gradient,makes their formations and strengths varied.The vortex breakdown deteriorates the stability and efficiency of compressor and fan.So a model of interaction between shock wave and leakage vortex is formulated.The solution of vortex core movement equations shows that the small initiative vortex core velocity and enhanced initiative vortex core pressure will induce the vortex instability.The high Mach number and circulation gradient outside the vortex core will result in breakdown of the vortex.The analysis of the factors leading to vortex breakdown serves as a foundation for its controlling. |
