摘要
介绍氢气泡流场显示技术原理以及试验用水槽及水洞等设备。通过试验,验证了此类试验中所用到的示踪粒子生成、照明等技术,并分析了相应的适用试验类型,然后介绍了该技术在旋成体附面层控制、压气机叶栅流场研究以及活塞发动机冷却腔体流场研究方面的应用。实践表明,该技术不仅可以直观地观察流场分布情况,并能定量得到流场中的速度分布信息。
In this paper,mechanism of technique of flow field display with hydrogen bubble is stated with the instruments including water tunnel and water channel used in test. Technique of generation of the traceable particle and lighting for flow field display is verified in the test,and the corresponding test type is analyzed. Then the application of this technique in rotation body boundary layer control,study on flow field of compressor blade cascade and piston engine cooling cavity is stated. Practice indicates that with this technique not only the distribution of flow field can be observed directly,but also the velocity distribution information in the flow field can be gained quantitatively.
