Experimental study on discharge characteristics and ozone generation of dielectric barrier discharge in a cylinder–cylinder reactor and a wire–cylinder reactor

The dielectric barrier discharge (DBD) reactors with a wire–cylinder configuration and a cylinder–cylinder configuration for ozone generation are investigated experimentally. The discharge characteristics of DBD in these two reactors are studied by measurement of their electrical discharge parameters and observation of their light-emission phenomena. The ozone concentration and ozone generation efficiency under different voltages are compared and discussed for both reactors. It is found that the discharge mode of DBD in the wire–cylinder reactor is different from that in the cylinder–cylinder reactor, and the ozone concentration and ozone generation efficiency depend highly on the applied voltage in both reactors.
