Interrelation between configuration of electrodes for induction electric charging and collector current wind EHD power generator

This work aims to realize a wind electrohydro- dynamical (EHD) power generator using induction electric charging with a water jet. The electrodes for induction electric charging are composed of an orifice of which inner radius is 1.5mm and a ring made of a copper wire of which diameter is 1.5mm. It is important to design the electrodes that maximize induction electric charge. In this paper, it is experimentaly clarified that the ring electrode of inner diameter of 3.7cm gives the collector short current of the wind EHD power generator more than that of 4.7cm but has dispersion of the collector short current more than that of 4.7 cm.
