Definition

Pressure-driven flow is bulk fluid motion resulting from either a globally applied difference (gradient) or an internally induced hydraulic pressure difference (gradient). Electroosmotic flow is the bulk liquid motion due to the interaction between an external electric field applied tangentially along a charged surface and the excess net charges in the electric double layer of such a charged surface. Specifically, the focus of this entry will be on the electroosmotic flow generated by an applied DC electric field only. In addition, the analysis of this entry is based on an assumption that the order of magnitude of the electroosmotic flow velocity is the same as that of the pressure-driven flow velocity. In the field of micro- and nanofluidics, the term combined pressure-driven flow and electroosmotic flow is referred to as the bulk liquid flow that is generated as a result of both pressure gradient and applied electric field.
