Abstract Electroosmosis is an effective method for liquid mixing. It is associated
with the motion of a liquid in a microchannel induced by an applied electric field.
In this manuscript, a numerical model is elaborated and implemented for the case
of a straight channel with a single electrode pair. In particular, the Navier-Stokes
equation combined with the Convection-diffusion and Helmholtz-Smoluchowski
equation are used to simulate the resulting flow field. The influence of various
electrode parameters on the mixing efficiency and the related mechanisms are
investigated. The numerical results show that a pair of eddies are produced alternately by the changing electric… More >
