Description

We study the inertial effects on contact line dynamics for liquid in partial wetting on several surfaces with low hysteresis. These surfaces have an imposed oscillatory motion entraining the liquid (whose upper part is pinned on an adhesive surface). We measure the dynamic contact angle as a function of the triple line velocity and relate the emerging hysteresis cycles to the oscillations and liquids properties.
