ABSTRACT:
An electrohydrodynamic (EHD) conduction pump is provided for pumping dielectric liquids, and a particular adaptation for mass transport of isothermal and non-isothermal single phase liquids. The EHD conduction pump does not require direct injection of electric charges into the fluid. The EHD conduction pump includes an EHD pumping section and associated connecting tubes with electrodes arranged in series in the pumping section. The electrodes are coupled to a high voltage low current dc power supply. A positive polarity dc voltage is applied to the electrodes. Various electrode configurations may be used, such as three-needle, hollow-tube, or pin-needle electrode configuration.
