Resumen en inglés

We propose an equation that describes the shape of the driven contact line in dynamics in presence of arbitrary (possibly random) distribution of the surface defects. It is shown that the triple contact line depinning differs from the depinning of interfaces separating two phases; the equations describing two these phenomena have an essential difference. The force-velocity dependence is considered for a periodical defect pattern. It appears to be strongly non-linear both near the depinning threshold and for the large contact line speeds. These nonlinearity is comparable to experimental results on the contact line depinning from random defects.< Leer menos
