摘要

我们考虑了夹持液滴的受迫振荡。液滴周围是密度不同的不可压缩流体。在平衡状态下，液滴呈圆柱形，轴向以平行固体平面为界，接触角为 90°。具体的边界条件如下：只有当接触角的偏差超过某个临界值时，接触线才会开始滑动。因此，可以观察到粘滑动力学。

Influence of contact angle hysteresis on forced oscillations of a clamped drop

We consider forced oscillations of a clamped liquid drop. The drop is surrounded by an incompressible fluid of a different density. In equilibrium, the drop has the form of a circular cylinder bounded axially by parallel solid planes, and the contact angle measures 90°. The specific boundary conditions are applied as follows: the contact line starts to slide only when the deviation of the contact angle exceeds a certain critical value. As a result, the stick-slip dynamics can be observed.
