Change in drag, apparent slip and optimum air layer thickness for laminar flow over an idealised superhydrophobic surface [PDF]
, 2013 Analytic results are derived for the apparent slip length, the change in drag and the optimum air layer thickness of laminar channel and pipe flow over an idealised superhydrophobic surface, i.e. a gas layer of constant thickness retained on a wall.

Equilibrium measurement method of slip length based on fluctuating hydrodynamics [PDF]
Physical Review E, 2020 We perform equilibrium molecular dynamics simulations for nanoscale fluids confined between two parallel walls and investigate how the autocorrelation function of force acting on one wall is related to the slip length. We demonstrate that for atomically smooth surfaces, the autocorrelation function is accurately described by linearized fluctuating ...

Lubrication Models with Small to Large Slip Lengths
Journal of Engineering Mathematics, 2005 A set of lubrication models for the thin film flow of incompressible fluids on solid substrates is derived and studied.The models are obtained as asymptotic limits of the Navier-Stokes equations with the Navier-slip boundary condition for different orders of magnitude for the slip-length parameter.

Electroviscous effect on fluid drag in a microchannel with large zeta potential
Beilstein Journal of Nanotechnology, 2015 The electroviscous effect has been widely studied to investigate the effect of surface charge-induced electric double layers (EDL) on the pressure-driven flow in a micro/nano channel.
