Characteristics of temperature distribution in atmospheric pulsed surface dielectric barrier discharge for ozone production

The temperature field distribution in air SDBD (surface dielectric barrier discharge) is investigated by measuring the temperatures of reactive plasma volume (T_p), electrode (T_e) and gas (T_g) using the fiber optic thermometer. Results show that T_p is almost the same as T_e, while T_g is lower than T_p. Both T_p and T_g follow a first-order model. The temperature in the area between the boundary of the plexiglass surfaces and the electrodes is higher than the temperature in the center. The gas flow rate has little effect on T_p due to that air flow is in steady laminar flow state.
