Abstract
⺠A series of numerical simulations is devised to study superhydrophobic surfaces obtained by random deposition of hydrophobic particles. ⺠The simulation method presented here is the first to predict performance of superhydrophobic surfaces with random microstructure. ⺠A new expression is developed for the critical pressure at which a submerged idealized granular superhydrophobic surface departs from Cassie state. ⺠The critical pressure increases with deceasing the porosity of the surface or size of the particles. ⺠Reasonable agreement is observed between our analytical and numerical predictions.
