Simulation of a Helium Atmospheric Plasma Jet Using Fluid Equations
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...
متن کاملHigh Voltage Pulsed Atmospheric Pressure Helium Plasma Jet
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 ...
متن کاملMolecular Effects of Atmospheric Pressure Plasma Jet on the Double-Stranded DNA
Introduction The aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (APPJ) and interactions of this technology with double-stranded DNA using the polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) techniques. Materials and Methods The plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...
متن کاملElectron properties in an atmospheric helium plasma jet
In this work we present Thomson scattering measurements on a nanosecond pulsed high voltage dielectric barrier discharge (DBD)-like helium plasma jet, operated in ambient air. With the low detection limit offered by a triple grating spectrograph equipped with a high quantum efficiency intensified charge-coupled device (ICCD) camera, temporally and spatially resolved electron densities and mean ...
متن کاملOn plasma parameters of a self-organized plasma jet at atmospheric pressure
Electron temperature and electron concentration in the active zone of a miniaturized radio frequency (RF) non-thermal atmospheric pressure plasma jet in argon have been determined using two independent approaches: the spectroscopic measurement of the broadening of Balmer Hβ and Hγ lines and a time-dependent, spatially two-dimensional fluid model of a single discharge filament. The plasma source...
