为研究Y型微通道内壁面滑移和连续相表观黏度对通道内液滴尺寸和流动特性的影响,采用水平集法进行数值模拟.结果表明：随着连续相通道滑移长度的增加,液滴长度增长,通道内流动更均匀.壁面滑移作用的范围占通道的46.8%.决定表观黏性系数的两参数增加,造成负滑移边界形成,促进液滴脱离,造成液滴长度缩短.表观黏度作用范围占通道的一半以上.对微流体混合系统的优化设计提供了参考.

英文摘要：

In order to investigate the influence of the wall slip and apparent viscosity of the con- tinuous phase on the droplet size and flow characteristics, in a Y-junction micro-channel, the level set method is used for numerical simulation. The results show that when the slip length in- creases in the continuous phase channel, the droplet length increases, and the velocity distribu- tion becomes evenly. The range of the boundary slip effect accounts for 46.8% of the channel. The apparent viscosity is determined by the two parameters. The negative boundary slip is formed, the droplet detachment is accelerated, and droplet length decreases for increasing the two parameters. The range of the apparent viscosity effect accounts for more than half of the channel. It provides a reference for the optimal design of the micro fluid mixing system.
