In this section, we employ the Young equation to parametrise surfaces with different degrees of hydrophobicity. As a benchmark, we use experimental contact angles of water droplets in dodecane in silica surfaces obtained by Andersson et al. In these experiments, silica wafers are modified with self-assembled monolayers (SAMs) of different compositions, affecting the wettability. Here, we take three combinations of -OH and -CH 3 coverages (see first and second columns in Table ) and propose a simple continuous wall model for each.
