Mesoscopic Modelling of Droplets on Topologically Patterned Substrates

摘要

We present a lattice Boltzmann model to describe the spreading of droplets on topologically patterned substrates. We apply it to model superhydrophobic behaviour on surfaces covered by an array of micron-scale posts. We find that the patterning results in a substantial increase in contact angle, from 110° to 156°.
