In the use of atmospheric pressure plasma jets in biological applications, the plasma-produced charged and neutral species in the plume of the jet often interact with a thin layer of liquid covering the tissue being treated. The plasma-produced reactivity must then penetrate through the liquid layer to reach the tissue. In this computational investigation, a plasma jet created by a single disch...

This paper describes a study where an argon cold plasma jet, generated by dielectric-barrier discharge (DBD), is combined with nanosecond laser ablation (248 nm, 25 ns, 10 Hz) to deposit silver particle aerosols onto the substrate at atmospheric pressure. The deposition of examined using various microscopy techniques and absorption spectroscopy for jet produced operating DBD in normal reversed ...

Abstract Disruptions in tokamak plasmas may lead to the generation of runaway electrons that have potential damage plasma-facing components. Improved understanding process requires interpretative modelling experiments. In this work we simulate eight discharges ASDEX Upgrade and JET tokamaks, where argon gas was injected trigger disruption. We use a fluid framework with capability model through ...

The double-peak structure observed in soft-hard hadron correlations is commonly interpreted as a signature for a Mach cone generated by a supersonic jet interacting with the hot and dense medium created in ultrarelativistic heavy-ion collisions. We show that it can also arise due to averaging over many jet events in a transversally expanding background. We find that the jet-induced away-side yi...

The energy-momentum tensor of a supersonic heavy quark jet moving through a strongly-coupled N = 4 SYM plasma is analyzed in terms of first-order Navier-Stokes hydrodynamics. We focus on the near zone “head” region close to the heavy quark where deviations from hydrodynamic behavior are expected to be large. For realistic quark velocities, v = 0.99, we find that the non-hydrodynamical head regi...

Arrays of atmospheric-pressure plasma jets are being considered as a means to increase the area being treated in surface modification and in plasma medicine in particular. A unique challenge of scaling plasma jet arrays is that individual plasma jets in an array tend to interact with each other, which can lead to quenching of some individual jets. To investigate these potential interactions, a ...

The paper presents an analysis of the heat transfer processes in electric arc plasma conditions between powder material and jet different convective states. generated for coating deposition are considered based on varying jet–powder interaction. formed deposited onto substrate acts as indicator efficiency. is facilitated by turbulent nature jet. presented calculation results demonstrate influen...

Gas phase non-equilibrium plasmas containing water vapor are of growing interest for many environmental and biomedical applications. Nonetheless the plasma kinetics that is of the utmost importance for these applications remain poorly understood [1]. A He-H2O reaction mechanism has been compiled and validated for a diffuse atmospheric pressure glow discharge [2]. Models of the more complicated ...

Two types of plasma jet systems working at low pressure and at atmospheric pressure are described. The system principles, main features as well as basic areas of their applications thin film depositions are given. Also, the different methods of discharge ignition in plasma jet systems continuous or pulsed DC or RF are reviewed. Selected advantages of plasma-aided technology are listed in the in...
