摘要
采用水-空气系统,研究了液体射流直径对双通道气流式喷嘴雾化性能的影响.结果表明：当液气质量比为0.82～5.48时,液体射流直径对雾滴直径有显著影响.在液气质量比一定的条件下,随液体射流直径的增加,雾滴直径呈先减小后增大的变化趋势.当液体射流速度为2～4 m/s时,雾滴直径最小.
The effect of liquid jet diameter on performance of two-fluid airblast atomizer was investigated in a water-air system. The experimental results show that liquid jet diameter has obvious effect on Sauter mean diameter （SMD） when water/air mass flux ratio is 0. 82-5.48. For a fixed water/air mass flux ratio, SMD reduces firstly and increases afterward with the increase of liquid jet diameter. The minimum SMD is obtained when the velocity of liquid jet flow is about 2-4 m/s.
