A numerical investigation of magnetic mixing in electroosmotic flows

In this study, the efficiency of passive mixing in an electroosmotic flow has been simulated numerically in the presence of a magnetic field which can potentially improve the mixing efficiency by applying a force normal to the flow direction. It is demonstrated that the mixing efficiency can be efficiently enhanced by effects of the magnetic field on the flow. The numerical results revealed that for flow at Reynolds of 0.02, the microchannel length of 100 μm and the maximum Peclet of 1.351 × 10–3, the applied magnetic field can increase the mixing efficiency from 70% to 90% in a given microchannel length. •A New scheme for passive mixing.•Magnetic Mixing in Electroosmotic Flows.•Increasing of mixing efficiency.•Nernst–Planck equations solving for the ionic concentrations.
