Slippage on hierarchical superhydrophobic surfaces (theory, simulation) The exceptional wetting properties of superhydrophobic (SH) surfaces [1] have motivated numerous applications in microfluidics. ... Recent experiments have shown that a hierarchical surface with nanoposts lying on the top of microposts does not necessarily lead to an increase in the effective slip length [5]. ... The main goal is to determine, how the effective slip length depends on the number of hierarchy levels. ...

... In a sphere-plane geometry, routinely used in atomic force microscope and surface force apparatus, it can form a bridge connecting the surfaces. ... By minimizing the free energy of a binary mixture we obtain the force-distance curves as well as the structural phase diagram of the configuration with the bridge. Numerical results predict a discontinuous transition between the states with and without the bridge and linear force-distance curves with hysteresis. ... Phys., Vol. ...

... The effect of effective slip is predicted to decrease the force as compared with what is expected for two hydrophilic surfaces and described by the Taylor equation. ... In a case of hydrophilic surfaces a hydrodynamic force reads [18] FT = 6U R h 2 when the gap h R .Here denotes a fluid dynamic viscosity. ... A corollary of this is that the effective hydrodynamic slip beff generally depends on the flow direction being a tensor [29] and that it also depends on the separation between surfaces [9,17]. ...
