Abstract

We use computer simulation to study the effect of surfactants on a drop spreading on a solid surface. Surfactants enhance spreading, especially when the hydrophobic head of the surfactant molecule is strongly attracted to the solid. A significant part of the spreading is due to the "shielding" of the surface by the surfactant. We use a novel boundary condition that reduces the simulation time by a factor of two.
