论文摘要
我们计算了正常的毛细管保留力，该毛细管保留力将滴落到垂直于表面的方向上的固体表面，并研究这种力与年轻的粘附工作之间的关系。我们还通过在固体基材上移动三重线来计算创建或破坏固定界面斑块所必需的工作。我们认为，当毛细血管数较小并且下降以恒定速度在表面上滑动时，横向保留力是能量耗散的主要来源，而粘性耗散作用起次要的作用。
We calculate the normal capillary retention force that anchors a drop to a solid surface in the direction perpendicular to the surface, and study the relationship between such force and the Young-Dupre work of adhesion. We also calculate the work necessary to create or destroy a patch of solid-liquid interface by moving the triple line on a solid substrate. We argue that when the capillary number is small and a drop is sliding on a surface at constant speed, the lateral retention force is the major source of energy dissipation, whereas viscous dissipation plays a minor role.
