Wetting behavior roughness effect

The effects of increasing surface roughness were experimentally determined to give reductions in non-wetting phase contact angles and reductions in the mobilization forces requirement. When composite surfaces form, roughened surfaces reduce the mobilization requirements when compared with those for smooth surfaces. This behavior could occur in porous media that has first been exposed to the wetting brine phase. [Pg.448]

MD simulations of the wetting of hydrophobic substrates with surface inhomogeneities displayed a similar behavior as hydrophobic rough surfaces, with high contact angles (>130° for fluid comprised of "small-chain" molecules). Upon application of a lateral push, the droplet detached from the surface, akin to the lotus effect but at the nanoscale. This was not observed with the simulations with a homogenous surface. [Pg.371]
