Concentration polarisation minimisation in membrane channels through electro-osmotic mixing by Liang, Yong Yeow

“…An electro-osmosis technique is proposed in this thesis which has the potential to reduce CP because it induces the movement of fluid in the vicinity of membrane, thus improving mixing within the boundary layer and enhancing mass transfer. Computational Fluid Dynamics (CFD) is used to simulate steady and unsteady electroosmotic flow (EOF) in 2D unobstructed and obstructed channels. …”
