Abstract

The characterization of electrohidrodynamic flow generation system (EHD) has been performed utilizing positive corona discharge configured wire-plate electrode. In this study, the characteristics of the EHD flow generation system in the form of current characteristics as a function of voltage or I-V characteristics with fixed geometry factor, in the without of lubricating oil and with the lubricating oil. The fixed geometry factor was obtained from the radius of the fixed point (r) electrode with various the electrode distance (d). This research was conducted by using positive corona incandescent discharges with wire field electrode configuration. The wire electrode used is made of stainless steel having a length of 5 cm, with wire diameter 0.11 mm, 0.14 mm, 0.21 mm, 0.36 mm, and 0.38 mm. Electrode of field used in the form of circle with diameter 20 cm. Data collection system with variation of voltage, variation of electrode distance, and variation of wire electrode diameter used. Furthermore, data analysis of measurement results was carried out. From the result of characteristic research of EHD flow generator system in the form of current as a function of voltage shows that the increase of voltage is proportional to current increase. While the current as a function of geometry shows the value of the current flowing inversely proportional to the geometry factor of the electrode distance change.Keywords:electrohydrodinamic, ion wind, positive corona discharge

Abstract

Determination of the ion wind angle of positive corona discharge with point to plane electrode geometry configuration has been done. Point electrode was made from stainless steel with various radiuses of 0.26 mm, 0.28 mm, 0.35 mm, and 0.47 mm. The plane electrode with circle form was made from stainless steel with diameter of 20 cm. Determination of the ion wind angle was carried out by measuring the current, the radius of deformation of lubricating oil at various voltage, electrode spacing, and the radius of the point electrode. The results showed that the angle of the ion wind direction is affected by a given voltage, the distance between electrodes, and the radius of the point electrode. Value of the ion wind flow direction angle is inversely proportional to the distance between the electrode and the radius of the point electrode. When the voltage is increased, the angle of ion wind direction will be larger but would reach saturation at the region of corona discharge which is close to the arc discharge.Keywords: Ion wind, positive corona discharges, point to plane electrode.
