论文摘要
提出了沿浓缩乳液中涡旋方向沿涡度方向形成的滴带形成。也就是说，观察到的各向异性结构的特征是高浓度的液滴区域与几乎没有任何颗粒的区域相互交织在一起的区域。这些颗粒分布明显地出现了以前报道的乳液。这些模式是由圆形平行板几何形状（CSS450-LINKAM）中简单流动的效果引起的，但仅在流动开始后长时间之后。也就是说，仅在乳液中出现其他各种现象之后才出现乳液中带中的条带的观察。也就是说，流动池板的分离为100μm，频带的观察发生在3.0至5.0 s^{ - 1}的剪切速率的间隔内，但仅在初始结构长时间演变后，一系列流量为0.75至2.25 s^{ - 1}。
The study of the formation of bands of drops along the direction of the vorticity in a concentrated emulsion is presented. That is, the observed anisotropic structures are characterized by regions of high concentration of drops interspaced with regions of about equal width where hardly any particles are present. These particle distributions are a clear departure to what has previously reported for this emulsion. These patterns are induced by the effect of a simple flow in circular parallel plate geometry (CSS450-Linkam), but only after a prolonged time after the inception of the flow. That is, the observation of bands in emulsions only appears after various other phenomena occur in the emulsion. That is, the separation of the flow cell plates is 100 μm, and the observation of bands occurs within the interval of shear rates of 3.0 to 5.0 s^{-1}, but only after a long evolution of the initial structure with a series of flows of 0.75 to 2.25 s^{-1}.
