Influence of electrostatic induction electrode configuration on water mist charging

Electrostatic atomization is the application of electric charge to produce fine drop from a liquid. It is said that electrostatic induction charging effects water mist charging by some parameter such as configuration of ring induction electrode, water pressure and applied voltage but still well unknown. So, to make it more clear, this research is done and focusing on configuration of ring induction electrode in water mist charging. In this study, a mechanism is proposed and mist nozzle is used to produce water mist. Variables of ring electrode diameter and its distance from the mist nozzle are examined as configuration of the ring induction electrode. When the water mist came out from the mist nozzle and went through the ring induction electrode, it will inducted by the applied voltage. Faraday cup is placed under the nozzle to collect the charged water mist. To determine the charge-to-mass of water mist, currents at ring induction electrode and faraday cup are measured. As a result, it is understood that the separation region and high charge-to-mass of water mist can be found on certain configuration of ring induction electrode. Besides, charge-to-mass quantity is higher in positive applied voltage rather than negative applied voltage.
