Comparison between super-hydrophobic, liquid infused and rough surfaces: a direct numerical simulation study

Direct numerical simulations of two superposed fluids in a channel with a textured surface on the lower wall have been carried out. A parametric study varying the viscosity ratio between the two fluids has been performed to mimic both idealised super-hydrophobic and liquid-infused surfaces and asses...
