  • Characteristics of Ozone Production by Pulsed Power 
    Samaranayake, W.J.M.; Miyahara, Y.; Katsuki, S.; Lisitsyn I; Hackam, R.; Akiyama, H. (12th IEEE International Pulsed Power Conference, 1999)
  • 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 ...
  • Ozone synthesis in a cylindrical dry air-fed ozonizer by non thermal gas discharges 
    Samaranayake, W.J.M.; Hackam, R.; Akiyama, H. (2003)
    Ozone is increasingly being used as an alternative oxidant to chlorination processes in various industrial applications without any objectionable by products to the environment and requiring less energy for its production. ...
  • Ozone synthesis in oxygen using a pulsed discharge 
    Samaranayake, W.J.M.; Hackam, R.; Akiyama, H. (2001)
    Ozone is a strong oxidizing and bleaching agent, which makes it a potent germicide, viricide and bactericide. Therefore, ozone can be used as an alternative to chlorination processes with low energy consumption and without ...
  • 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 ...
