| Abstract: | When a solid plate is withdrawn from a liquid bath, a receding contact line
is formed where solid, liquid, and gas meet. Above a critical speed Ucr,
a stationary contact line can no longer exist and the solid will eventually
be covered completely by a liquid film.
Here we show that the bifurcation diagram of this coating transition
changes qualitatively, from discontinuous to continuous, when
decreasing the inclination angle θp of the plate.
We show that this effect is governed by the presence of capillary
waves, illustrating that the large scale flow strongly effects the
maximum speed of dewetting. |
