Generalization of interfacial electrohydrodynamics in the presence of hydrophobic interactions in narrow fluidic confinements.
We show that the interfacial electromechanics in narrow fluidic confinements exhibits a universal dependence with the intrinsic surface-wettability characteristics, independent of the details of the bulk flow actuating mechanisms. Towards this proposition, we develop a generalized mesoscale model, which is extensively tested for combined electro-osmotic and pressure-driven nanochannel flows. Agreement with the molecular dynamics simulations is found to be quantitative.
