Numerical investigation of gas heating effect in dielectric barrier discharge for Ne-Xe excilamp

The purpose of this paper is to study the gas heating phenomenon in dielectric barrier discharge (DBD) due to the Joule heating effect for Ne-Xe gas mixtures. In this work, the simulation was performed using a one-dimensional fluid model. The gas temperature profile was calculated by heat conduction equation resolution along gap distance of discharge. The increasing of gas temperature close to the vicinity of cathode is due to the high values in the power deposited in this region. The results show that the gas temperature in DBD excited with rectangular applied voltage waveform is more important than the discharge created by a sinusoidal excitation. For high values of secondary electron emission coefficient (γ) the gas temperature will be increasing. The effect of varying gas mixture composition on gas temperature has been also examined.
