ELECTROHYDRODYNAMIC PUMPING PRESSURE GENERATION Public
Downloadable Contentopen in viewer
Electrohydrodynamic (EHD) conduction pumping relies on the interaction between electric fields and dissociated charges in dielectric fluids. EHD pumps are small, have no moving parts and offer superior performance for heat transport. These pumps are therefore able to generate high mass flow rates but high pressure generation is difficult to achieve from these devices. In this Major Qualifying Project, a macro-scale, EHD conduction pump capable of generating up to 400 Pa per section was designed, built and tested. The pump is comprised of pairs of porous, 1.6mm wide high-voltage electrodes with a pore size of 10µm and 3.7mm long flush, ring ground electrodes, spaced 1.6mm apart. The space between pairs is 8mm, with 8 pairs per section. The working fluid is the Novec 7600 engineering fluid.
