摘　　要：本文在雾化槽喷嘴出口处雾化特性的研究基础上,进一步利用激光全息测量了雾化槽下游的油雾场.比较、分析了雾化槽喷嘴油雾场在运动过程中,雾化性能的变化情况.讨论了雾化槽喷嘴宽度、喷嘴直径和气流速度等参数变化对雾化性能的影响.Based on the study on spray characteristics at the exit of a gutter-atomizer,the spray concentration distribution down stream from the gutter-atomizer is measured by means of laser holography .In this paper the variation of atomiza-tion performance in the spray is studied, and the effects of the width of gutter, the diameter of atomizer and the air speed on the atomization performance is also discussed.
