| 摘 要： | 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LDV/APV系统),通过观察和测量细水雾被射流卷吸的现象,荻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.

| Abstract: | The Laser Doppler Velocimetry (LDV)or Adaptive Phase Doppler Velocimetry(APV) system was used to study the water mist flow field induced by a jet. The water mist characteristics:mean velocity,volume mean size and volume flux were obtained.This experiment deepened the understanding of the mechanics of water mist induced by a jet and provided batter conditions for experiment of water mist induced by flame in the next step. |

| Keywords: | LDV/APV system water mist induce characteristic parameter |
