| 摘 要： | 研究了粘性流体在三通道气流式喷嘴的雾化过程,考察了三通道喷嘴雾化性能的影响因素。实验及数值模拟结果表明,当其他条件不变时,雾化滴径随液体粘度的约0.088次方单调增大,随液体流量的约0.37次方单调增大,随一、三通道气量比α的增加,呈现先增后减的非单调变化趋势,在α≈0.22时Sauter平均直径SMD达到最大值。

| Abstract: | Atomization process of viscous fluid by using airblast three-channel nozzle and effects of different factors on this process was investigated based on the experiment.The experimental and simulative results showed that when other test conditions are invariable,Sauter mean diameter SMD∝μ~(0.088) and ∝m~(0.37).When total air flow and liquid flow as well as liquid viscosity are fixed,the drop diameter increases firstly and decreases afterward with the(increasing) of gas flow distribution ratio α in No.1 and No.3 channels,and SMD gets maximum when the(value) of α is about 0.22. |
