喷雾液动态表面张力与雾滴粒径关系(Correlations between Dynamic Surface Tension and Droplet Diameter)
动态表面张力 雾化 雾滴
2009/9/11
为了描述喷雾液的动态表面张力与雾滴粒径的关系,用粒度分析仪对不同表面张力喷雾液喷雾时形成的雾滴体积中径D50进行了研究,重点考察了喷头尺寸、喷雾压力对D50的影响。结果表明:喷雾液0.023s时的动态表面张力值γ0.023越低,所形成的雾滴D50越小,D50与γ0.023呈线性相关;喷雾压力相同时,随着喷头尺寸的增大,喷雾液动态表面张力的改变对雾滴粒径的影响增大;喷头尺寸相同时,随着喷雾压力的增大...
