Spreading of a liquid bridge

ORAL

Abstract

We observe the spreading of a liquid bridge under a horizontal surface. After being pulled up to twice its capillary length, a bridge is formed between a liquid bath and a flat horizontal surface. This bridge then spreads radially over a large range (several centimeters) at a constant speed: the radius of the bridge $r$ progress linearly with the time ($r \sim t$). We study experimentally the parameters impacting the spreading, and develop a theoretical analysis to model the dynamics.
