Fluid transport in microfluidic devices induced by application of an electric field between two ends of a channel, called electroosmosis, is an important technique used in biomedical devices. Often, mixing of flow in nanochannels is difficult to achieve. However, mixing in these nanochannels can be facilitated by using non-uniform surface potentials on the walls. The objective of this project is to determine whether non-uniform surface potentials are of use in mixing flow in nanochannels.
