Modeling oil–water separation with controlled wetting properties

Several oil–water separation techniques have been proposed to improve the capacity of cleaning water. With technological possibility producing materials with antagonist wetting behavior, for example, a substrate that repels water and absorbs oil, understanding properties control this selective has increased goal being used as mechanism separate mixed liquids. Besides experimental advance in field, less is known from theoretical side. In work, we propose model predict given introduce simulations four-spin cellular Potts study its efficiency separating oil. Our results show substrates depends both on interaction between liquids behavior itself. The droplet composed roughly controlled by hydrophobicity substrate. Predicting oil however, more complex because oleophilic does not guarantee total amount present will be absorbed For types considered pillared porous reservoir, there always an reminiscent droplet, which due gas. Both numerical models can easily modified analyze other
