Abstract

The aim of this research is study of Electrohydrodynamic (EHD) flow by discharge corona generator with electrodes configuration of Pin- Dual Ring Concentric. We measured the velocity of EHD flow with electrodes configuration of Pin- Dual Ring Concentric and compare the result to Pin-Single Ring electrodes. The pin needle was made by stainless steel with a length of 50 mm and a tip diameter of 0.01 mm. The dual ring electrodes constructed by two metal material connected to each other with diameter of 24 mm and width of 16 mm. The thickness of rings is 2 mm and 3 mm, respectively. Single ring electrode has diameter, width and thickness of 24 mm , 2 mm and 3 mm, respectively. The EHD was generated by using a DC high voltage of 10 kV. The Pin act as an active electrode of corona discharge and concentric rings dual / single ring electrodes act as ions collector and passive electrodes. The velocity of EHD flow was measured by a Hot - Wire Anemometer. We found that the velocity of EHD flow with electrodes configuration of pin-dual ring concentric electrodes is larger than pin-single ring electrode. The velocity of EHD flow for two cases of electrodes configuration were saturated at the certain spacing of inter-electrodes distance. The maximum velocity of the of EHD flow using electrodes configuration of pin-dual rings concentric was 0,6 m/s at a distance of inter-electrodes distance 6 mm and a voltage of 3,2 kV.
