Hot wire test on the flow fields in a rotating square channel

  • 摘要: 为了解决旋转条件下热线技术应用问题并且在此基础上精确测量旋转方形通道内部流场特性,搭建了用于旋转通道流场测试实验平台,采用了两种连线方式对热线进行了标定实验,获得了热线测量旋转通道内部平均速度的相对误差为±6%,对雷诺数和旋转数范围分别是5000~10000和0~0.222的旋转通道流场进行了测量,结果表明:旋转导致速度型整体向后缘面(Y/D=-0.5)偏转,X/D和旋转数越大,速度型偏转越明显;旋转数为0.222时,后缘面附近边界层速度型出现了一个拐点,可能与由哥氏力不稳定性引起的二次流有关.
