本文利用三维激光多普勒测速计和自适性相位多普勒速度计系统 (三维 L DV/APV系统 ) ,通过观察和测量细水雾被射流卷吸的现象 ,获取了细水雾的平均速度、平均粒径和雾通量等特性参数 ,深化认识细水雾被射流卷吸的机理 ,为下一步进行细水雾被火焰卷吸现象的实验研究打下了良好的基础
In this paper, by using the three-dimensional laser Doppler velocimetry and adaptive phase Doppler velocimetry system (three-dimensional L DV / APV system), by observing and measuring the phenomenon that the water mist is entrained by the jet, the average water mist Speed, average particle size and fog flux and so on. Therefore, deepening the understanding of the mechanism that the water mist is entrained by the jet lays a good foundation for the experimental research on the water entrainment by the flame in the next step
