Abstract

Some surfaces exhibit wall slip, meaning that a owing uid has a velocity relative to that surface. This leads to increased advection in the direct vicinity of the wall. As this directly a ects the rate of transport at larger scales, slippery surfaces have a potentially important application in enhancing interfacial transport. The knowledge obtained through fundamental investigations of these micro- and nanoscale transport phenomena is therefore of high importance. The aim of this thesis is to extend the current knowledge on transport near slippery and/or heterogeneous interfaces. For that purpose, various experimental, analytical and numerical studies have been performed. The following topics have been investigated: - the in uence of hydrodynamic slip on momentum and mass transfer over superhydrophobic surfaces, focusing on a so-called bubble mattress; - the extension of a classical forced-convection problem to homogeneously and heterogeneously slippery surfaces, describing heat and mass transfer near these surfaces; - ion transport near heterogeneous, charge-selective interfaces in a micro uidic desalination device.
