Windage heating experiment on rotating disc in cavity of rotor-stator system

  • 摘要: 采用红外测温技术对转静系盘腔转盘风阻温升特性进行了实验研究,利用高速旋转实验台测量了不同流动参数以及转静间隙比下转盘各半径处的壁面温升,并研究了径向出流处增加封严环对于转盘温升量的影响.同时通过CFD数值模拟得到转静系盘腔内流动特点.结果表明:由于风阻引起转盘温升量实际上就是转盘的绝热壁温与环境温度之差,并能通过红外热像仪准确测量.针对无封严开式转静系,转盘温升量主要受到旋转影响,仅在小转静间隙比时,通流的变化才会影响风阻温升.总体上,转静间隙比的改变对转盘温升影响不大.与封严转静系对比可知,在湍流参数较小的情况,封严环的引入会使转盘温度有所升高.
