The present work deals with the electroosmotic mixing of chemical species in a circular nano-channel using Nernst Plank model.

The present model has the flexibility to handle multivalent ions and no symmetric conditions will be assumed at the centerline.

The pressure and vertical flow variation has been found in the transverse flow direction.

A strong pressure gradient is developed above the overpotential region which increases the mixing performance.

The streamlines and mole fraction distribution follows a tortuous path above the non-uniform potential for both weak and strong solution.
