Corners, Cusps, and Pearls in Running Drops
Journal Article

· Physical Review Letters
Small drops sliding down a partially wetting substrate bifurcate between different shapes depending on their capillary number Ca . At low Ca , they are delimited by a rounded, smooth contact line. At intermediate values they develop a corner at the trailing edge, the angle of which evolves from flat to 60{sup o} with increasing velocity. Further up, they exhibit a cusped tail that emits smaller drops (''pearls''). These bifurcations may be qualitatively and quantitatively recovered by considering the dynamic contact angle along the contact line.
