Abstract: | We present a mesoscopic model for simulating the dynamics of a non-volatile liquid on a solid substrate. The wetting properties
of the solid can be tuned from complete wetting to total non-wetting. This model opens the way to study the dynamics of drops
and liquid thin films at mesoscopic length scales of the order of the nanometer. As particular applications, we analyze the
kinetics of spreading of a liquid drop wetting a solid substrate and the dewetting of a liquid film on a hydrophobic substrate.
In all these cases, very good agreement is found between simulations and theoretical predictions. |
