  • Ozone generation in dry air using pulsed discharges with and without a solid dielectric layer 
    Samaranayake, W.J.M.; Miyahara, Y.; Namihira, T.; Katsuki, S.; Hackam, R.; Akiyama, H. (IEEE Transactions on Dielectrics and Electrical Insulation, 2001)
    Energy efficient generation of ozone is very important because ozone is being used increasingly in a wide range of industrial applications. Ozonizers usually use dielectric barrier discharges and employ alternating current ...
  • Ozone production using cylindrical reactors with and without solid dielectric layers in dry air 
    Samaranayake, W.J.M.; Miyahara, Y.; Namihira, T.; Katsuki, S.; Hackam, R.; Akiyama, H. (1999)
    An investigation into ozone production in dry air-fed ozonizers under different operating gas discharge conditions at a pressure of 1.01?105 Pa using a spiral wire made to a cylindrical configuration is reported. A magnetic ...
  • Ozone production using pulsed dielectric barrier discharge in oxygen 
    Samaranayake, W.J.M.; Miyahara, Y.; Namihira, T.; Katsuki, S.; Hackam, R.; Akiyama, H. (IEEE Transactions on Dielectrics and Electrical Insulation, 2000)
    The production of ozone was investigated using a dielectric barrier discharge in oxygen, and employing short-duration pulsed power. The dependence of the ozone concentration (parts per million, ppm) and ozone production ...
  • Pulsed power production of ozone in O2/N2 in a coaxial reactor without dielectric layer 
    Samaranayake, W.J.M.; Miyahara, Y.; Namihira, T.; Katsuki, S.; Hackam, R.; Akiyama, H. (IEEE Transactions on Dielectrics and Electrical Insulation, 2001)
    Very short duration pulsed streamer discharges have been used to produce ozone in a gas mixture of nitrogen and oxygen at atmospheric pressure. The ratio of nitrogen to oxygen in the mixture was varied in the range from ...
  • Pulsed power production of ozone using nonthermal gas discharges 
    Samaranayake, W.J.M.; Miyahar, Y.; Namihira, T.; Katsuki, S.; Sakugawa, T.; Hackam, R.; Akiyama, H. (IEEE Transactions on Dielectrics and Electrical Insulation, 2001)
    This paper discusses ozone synthesis by employing a short duration (?120 ns) of pulsed power and using positive voltages in dry air and in oxygen, with and without a dielectric barrier. Ozone concentration and ozone ...
  • Pulsed streamer discharge characteristics of ozone production in dry air 
    Samaranayake, W.J.M.; Miyahara, Y.; Namihira, T.; Katsuki, S.; Sakugawa, T.; Hackam, R.; Akiyama, H. (IEEE Transactions on Dielectrics and Electrical Insulation, 2000)
    Experimental investigation of HV short pulsed streamer discharges in dry air-fed ozonizers under various operating conditions are reported. Ozone concentration, energy input and ozone production yield (efficiency) were ...
