摘要
介绍了现代流动测试技术的特点、发展趋势及本课题组在流体动力设备研发方面的应用研究工作。主要工作有:热线风速仪技术(HWA)用于离心压缩机扩压器流场测试研究、用于湍流边界层的减阻控制研究;粒子图像速度场仪技术(PIV)用于叶轮机械动静相干非定常流场的研究、用于管道内横向射流的研究;激光多普勒测速仪技术(LDV)用于风机叶轮流场的测试研究等。
The feature and trend of modern flow instrumentation have been introduced together with the investigation in applied flow dynamic instrumentation. They are hot-wire anemometry (HWA) (for flow field measurement of centrifugal compressor and for damp reduction investigation in turbulence boundary layer); particle imaging velocimeter (PIV) (for the investigation in the interference of dynamic and steady state flows in turbo machinery); and laser Doppler velocimeter (LDV) (for flow field measurement of blower), etc.
