Abstract:

This paper presents the simulation of electrohydrodynamically driven micropump obtained by using 3D finite difference method. EHD governing equations are discretized and then explicitly defined for output parameters. A 3D prototype of ion-drag micropump with symmetric electrodes is modeled and simulated for the velocity, the pressure, electric potential and electric field. The objective of this study was to evaluate the results obtained by finite difference method (FDM) with the results obtained by a finite element method (FEM) based simulation package COMSOL Multiphysics. The comparison reveals that the numerical simulation results obtained by both the methods are appreciably close to each other. The simulation results are also compared with the existing experimental data and it was found that there are not high discrepancies between simulation and experimental results. The paper concludes that in case of regular geometries of ion-drag micropump the FDM is easy to implement and provides more control on different parameters involved in the simulation as compared to built-in finite element method based package.
