description: The topic of the graduate qualification work is âInvestigation of physical and chemical properties of the Ar dielectric barrier discharge at atmospheric pressureâ. The aim of this work is on the one hand to design and assembly the experimental setup of the atmospheric pressure dielectric barrier discharge (DBD) plasma-jet and on the other hand to clarify some physical and chemical processes in DBD plasma according to the optical emission spectrometry. On the base of the worldwide experience of the use of plasma-jets own apparatus consisted of high- - Ttage generator and the jet itself were created. Optical emission spectras of the plasma were obtained and the chemical composition of the plasma was proposed. The dependences of the intensity of some Ar, O and N lines on the technological parameters (applied voltage, Ar gas velocity and interelectrode space) were determined. All experimental was carried out in SPbSTU laboratories. Mathematical modelling of plasma gas dynamics in plasma jet in Comsol Multyphysics was carried out and dependences of the gas velocity on different parameters were determined.
