Abstract:
Mathematical models are set up for the electro-osmotic pump in this paper. The meshless algorithm is used to solve the Laplace equation, Poisson-Boltzmann equation and Navier-Stokes equations. The numerical results agree well with the closed form solution under low ζ potential, which proves the validity of the numerical solution. The simulation also uncovers the driven process of the micro-flow. It is demonstrated that the flat flow can be formed in a straight micro-tube acted by the external voltage. The flow rate is proportional to the external voltage and the ζ potential. This model can be used to analyze the micro-pumps with complex geometrical shapes.
