Electroosmotic flow of Maxwell fluid in a microchannel of isosceles right triangular cross section

Abstract

This work is presented to study the unsteady oscillatory electroosmotic flow of Maxwell fluid in a microchannel of an isosceles right triangular cross section. An external time-dependent electric field is applied and high zeta potential conditions are considered. Due to the difficulty of theoretical solution, a numerical method is adopted. The numerical solutions are derived by employing the finite difference method. Finally, the effects of some dimensionless variables, the relaxation time, the angular Reynolds number, the wall zeta potential, and the ratio between the typical length and the Debye length on the velocity profiles, are interpreted graphically.
