Drops sliding down an incline at large contact line velocity: What happens on the road towards rolling?

Laurent Limat

Résumé

Drops sliding down an incline exhibit fascinating shapes, which indirectly provide a great deal of information about wetting dynamics. Puthenveettil, Kumar & Hopfinger (J. Fluid Mech., vol. 726, 2013, pp. 26-61) have renewed this subject by considering water and mercury drops sliding at high speed. The results raise puzzling questions: how to take into account inertia at a high-speed contact line, large contact angles, the nature of the dissipation at small scale and sliding versus rolling behaviours?
