Atmospheric pressure plasma jet based on the dielectric barrier discharge

Abstract

The dielectric barrier discharge has attracted the interest of many researchers in several fields since it produces a non-thermal plasma at atmospheric pressure. Its field of application is totally vast and includes medicine, biotechnology, chemistry, and various other fields of science and technology because of the physical and chemical properties that characterize the plasma jet based on the dielectric barrier discharge. These are characterized by different possible configurations and can be powered by radio frequency, alternating current, and even pulsed direct current depending on the application. In this work, we have presented the atmospheric pressure plasma jet as a new micro discharge that can be used in several fields. We have presented the different possible configurations of the plasma jets based on the dielectric barrier discharge that vary according to the targeted application field. In addition, we have presented some fields of study and specialties in the different application areas such as medicine, biotechnology and food preservation, agriculture and combustion domains. Finally, we have presented the results of the simulation with COMSOL Multiphysics of a dielectric barrier discharge at atmospheric pressure for different frequencies and different discharge gaps between the electrodes, since this is the discharge used in the plasma jet.
