Electrical Potential, Mass Transport and Velocity Distribution of   Electro-osmotic Flow in a Nanochannel by Incorporating the Variation of   Dielectric Constant of Aqueous Electrolyte Solution
  We consider a coupled system of Navier Stokes, Maxwell Stefan and Poisson Boltzmann equations by incorporating the variation of dielectric constant, which governs the electro osmotic flow in nano channel, describing the evolution of the velocity, concentration and potential fields of dissolved constituents in an aqueous electrolyte solution. We apply the finite difference technique to solve one and two dimensional systems of these equations. The solutions give an extremely accurate prediction of the dielectric constant for a variety of salts and a wide range of concentrations.
