Abstract

The aim of this research is analysis electrohydrodynamic (EHD) phenomenon deformation of oil silicon surface by technology of positive corona glow discharge plasma which generated by plasma generator system with point-to-plane electrodes geometry configuration. The aim of this research is analysis of electrohydrodynamic (EHD) Phenomenon oil deformation of silicon surface by the technology of positive corona Which plasma glow discharge plasma generated by the generator system with point-to-plane electrodes geometry configuration. Variation of voltage and distance between electrodes had been treated to surface of silicon oil. Variation of voltage and distance Between electrodes Had been treated to surface of silicon oil. EHD phenomenon deformation in this research is caused by polarization and ion wind. Ionic wind would be happened if applied voltage over the corona threshold that was 2.6 kV. Phenomenon EHD deformation in this research is caused by Polarization and the ion wind. Ionic wind Happened would be if the voltage applied over the corona That threshold was 2.6 kV. Graph current of saturation corona unipolar for variation voltage, being formed semi-parabolic equation while the variation of distance between electrodes, being formed linear equation. Graph of the saturation current for the corona unipolar voltage variation, being formed a semi-parabolic equation while the variation of distance Between electrodes, being formed of linear equation. The hole diameter at variation voltage was influenced by electrics field intensity and moment dipole strength. The hole diameter at voltage variation was influenced by electrics field intensity and dipole moment strength. The hole diameter at variation of distance between electrode was influenced by parabolic angle of electrics line field. The hole diameter at variation of distance Between electrode was influenced by parabolic field line angle of electrics. The oil velocity for back to initial position is different. The oil velocity For a back to the initial position is Different. Velocity would be go down if the voltage progressively go up and velocity would be go up if the distance between electrode progressively go up. Velocity would be to go down if the voltage progressively go up and velocity would be to go up if the distance Between the electrode progressively go up.
