Synergy between injection and dissociation mechanisms in electrohydrodynamic pumps modeled numerically

This paper reports a numerical investigation into the effects of interactions between two mechanisms of charge injection and dissociation on overall Electrohydrodynamic (EHD) pump characteristics. The following three types of electrode configurations are modeled: a plate and a bar, two plates on a channel wall, and embedded two-plate electrodes. The simulation results show that when the both mechanisms act in concert, the total developed pressure is augmented to be larger than the sum of the pressures developed by each mechanism separately. The degree to which the pressure is synergistically augmented depends on the configuration of electrodes.
