Abstract
The results of investigations of electrohydrodynamic (EHD) flows using the schlieren method in the following systems of electrodes are presented: “blade–insulated edge blade,” “blade–two rods,” and “rod with perforated insulation coating–two rods.” Single-stage EHD pumps were designed on the basis of the obtained results. The pressure-flow characteristics of the pumps were studied depending on various factors. It was shown that the performance of the EHD pumps can be increased applying dielectric coatings to the electrodes. The maximum efficiency was obtained in the “blade–blade with insulated edge” system of electrodes, while the maximum static pressure was obtained in a three-rod system with a perforated insulation coating of the emitter. The advantages of a three-rod system were specified as regards to the improvement of the flow characteristics of the pump due to the parallel arrangement of the electrodes and the increase in the pump pressure when using multistage pumps with grid electrodes.
