Abstract
The electroosmotic flow induced by an applied electrostatic potential field through microchannels between two parallel plates is analyzed in this work. A non-linear, two-dimensional Possion-Boltzman equation governing the electrical double-layer field and the Laplace equation governing the electrostatic field distribution in microchannels are numerically solved using finite volume method by a PC cluster with parallel processing. The body force caused by the interaction between the electrical double-layer (EDL) field, and the applied electrostatic field on the fluid velocity distribution is discussed. The numerical results show that the electrical double-layer (EDL) field and the velocity field distribution are agreed well with the analyzed solution under the conditions of steady state and small zeta potential.
