Ac Corona Discharge Modes
In this paper a survey study has been made of ac corona discharge modes generated in some different gases fed in a wire duct reactor with a constant rate of flowing at atmospheric pressure.
Ac corona discharge modes. Ra el koramy a yehia m omer. Corona discharges in gases exist under several distinctive forms. Apci is a soft ionization method similar to chemical ionization where primary ions are produced on a solvent spray. Physics of plasmas 19 3 033513 2012.
Electric glow discharge is a type of plasma formed by passing a current at 100 v to several kv through a gas usually argon or another noble gas. Complete electrical breakdown of air insulation between two. Development of ac corona discharge modes at atmospheric pressure. Partial breakdown of air insulation occurring in the high electric field region generally in the vicinity of conducting surfaces but sometimes also near insulating surfaces due to ionization processes in the air.
Corona is an electrical discharge i e. In this paper a survey study has been made of ac corona discharge modes generated in some different gases fed in a wire duct reactor with a constant rate of flowing at atmospheric. A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically charged spontaneous corona discharges occur naturally in high voltage systems unless care is taken to limit the electric field strength. Atmospheric pressure chemical ionization apci is an ionization method used in mass spectrometry which utilizes gas phase ion molecule reactions at atmospheric pressure 10 5 pa commonly coupled with high performance liquid chromatography hplc.
A corona will occur when the strength of the electric field potential gradient around a conductor is high enough. In this paper a survey study has been made of ac corona discharge modes generated in some different gases fed in a wire duct. The properties of different corona modes are analyzed under some condition transitions from trichel pulses to a steady glow. Corona discharges in gases exist under several distinctive forms.
Their combined citations are counted only for the first article. Expectation of ozone generation in alternating current corona discharges. Corona discharges in gases exist under several distinctive forms. Physics of plasmas 18 2.
