Abstract
In the present study, the effect of slip boundary condition on the rotating electroosmotic flow (EOF) of Oldroyd-B fluid in a microchannel under high zeta potential is considered numerically. The potential distribution of the electric double layer (EDL) is acquired by solving the nonlinear Poisson-Boltzmann equation. The numerical solution of velocity profile is obtained by using a finite difference method. The effects of rotating Reynolds number, electric width, viscous parameter, slip parameter etc on velocity and boundary stress for Oldroyd-B fluid EOF are discussed, which show that the slip boundary effect can reduce the boundary stress and promote the development of flow.
