We introduce the governing equations of flow in a microchannel, which is driven by electroosmotic force, and develop a calculation method based on the finite difference control volume method. The nondimensional equations are introduced based on the width of the microchannel and the characteristic velosity; U_E = εζΔφ/μL, where ε, ζ, Δφ, μ and L are, respectively, the dielectric constant of the solvent, the zeta potential of the electrical double layer at the solvent - wall interface, the external electric potential difference, the dynamic viscosity and the width of the microchannel. We propose a fluid mixing method in a microchannel utilising electroosmotic force, which seems to be quite efficient and realistic.
