To research traveling wave electroosmotic(TWEO) driving microflow
simulation and experimental analysis for TWEO flow in a closed microchannel are explored. From the charge distribution in the double electric layer
a nonlinear model for TWEO pumping microflow is presented. Through solving the electric field and velocity field problems
the velocity field simulation is presented in a closed microchannel. Contrasting with the experimental result
the theory for the model is verified. The velocities on the 2/3 height in the microchannel are showed in simulations and experiments
the results show the relation between velocity and frequency satisfy normal distribution. These results offer a basis for further researching TWEO pumping microflow and it application in lab on a chip.
