Studies on Electroosmotic Flow through a Microchannel between Two Parallel Plates without the Debye-Huckel Approximation: An Analytical Approach

In the present work, a simple analytical method for obtaining solutions for the understanding of fundamental characteristics of electroosmotic flow through a parallel plate microchannel without the Debye-Huckle approximation is presented. Hence, Poisson-Boltzmann equation without the Debye-Huckle approximation for the electric potential distribution, the Navier-Stokes equation for the velocity profile and the energy equation for temperature distribution are averaged and solved analytically using homotopy perturbation method. Homotopy perturbation method (HPM) is simple, powerful, efficient and more accurate analysis is possible using it. The electric potential distribution, the velocity and temperature profiles are plotted and studied for a certain range of zeta potential.
