This paper describes the concept of Electrohydrodynamic (EHD) pumping in microchannels and the study of EHD pumps in IntelliSuite's Microfluidic simulation module. The EHD pump study focuses on the factors influencing the velocity of fluid flow such as the conductivity of the fluid, the frequency of the driving AC voltage, the phase of the driving signal, the dimensions of the electrode, the gap between the electrodes and the the number of driving electrodes. The results from the simulation will be used to characterize the presented design of the EHD pump. The presented design for the study of the EHD pump has a microchannel with a length of 0.2mm, width of 0.08mm and a thickness of 0.08mm. The width of the driving electrodes present at the bottom of the channel is 0.01mm and the gap between the electrodes is 0.04mm.
