In this study, a cold atmospheric He plasma jet is investigated. The jet is of dielectric barrier discharge type, consisting of a dielectric tube with two metal ring electrodes. The continuity, momentum and energy conservation equations as well as the Poisson equation for obtaining the potential and the electric field, accompanied with the ideal gas laws, are used for the simulation. The result...
The RF plasma slit jet, which produces 150 mm wide streaming outside the jet body, exhibits exciting self-organization phenomena that resemble self-organized patterns of dielectric barrier discharge (DBD) filaments. Similarly, as in DBD, filaments are surrounded by an inhibition zone does not allow two to come closer each other. With fast camera imaging, we observed filamentary character all st...
In this work, we first produced microwave plasma ball, then changed the ball into a microwave plasma jet by flowing a working gas through a nozzle. The effect of working gas on the thermal characteristics of the plasma ball and atmospheric pressure microwave plasma jet was investigated. We used resonant absorption scheme by a metallic antenna inside a chamber in which led to the ionization of s...
Non-equilibrium cold plasma jets generated under atmospheric pressure by means of high voltage pulsed power generator are extended up to a few centimeters long in the surrounding air. The generator is consisting of a negative dc source, a Blumlein-type pulse-forming network (E-PFN), and a dynamic spark gap switch. The plasma jet generated by the device using helium as the operating gas depends ...
