Abstract Erosion of an aluminium oxide surface as well a formation coating on substrate, comparable with erosion and induced by plasma electrolytic oxidation (PEO), can be caused at atmospheric pressure conditions DBD-like (Dielectric Barrier Discharge) jet. Obtained experimental results conform previously assumed similarity the mechanisms jet PEO microdischarges. The mechanism predominantly in...

The operational characteristics of the experimental direct current plasma torch with water vapor stabilization of the arc discharge and diagnostics of generated plasma jet at the nozzle exhaust of the torch were studied in this research. The operation parameters of the torch are presented in terms of generalized thermal and electrical characteristics, which were compared with equations for stea...

This article aims to address the issue of simulating plasma-jet by using an innovative computational approach namely the Lattice Boltzmann Method (LBM) from the point of view of extending the applications to simulating flows with temperature-dependent physical parameters. The work focuses on the phenomena occurring in plasma-jet that define the link between LBM lattice and physical lattice. Hig...

In the past few years, the bactericidal effect of atmospheric pressure plasmas have gained significant attention in dermatology and for application like the sterilisation of heat sensitive medical devices such as endoscopes, dentist and surgical tools. Previous research performed at the TUe by van Gils et al has shown that plasma induced liquid chemistry is important in the inactivation of bact...

Aims. The theoretical model for magnetohydrodynamic (MHD) modes guided by a field-aligned plasma cylinder with a steady flow is adapted to interpret transverse waves observed in solar coronal hot jets, discovered with Hinode/XRT in terms of fast magnetoacoustic kink modes. Methods. Dispersion relations for linear magnetoacoustic perturbations of a plasma jet of constant cross-section surrounded...

Observation of a large density amplification in the collimating plasma jet ejected from a coplanar coaxial plasma gun is reported. The jet velocity is ∼30 km s−1 and the electron density increases from ∼1020 to 1022–23 m−3. In previous spheromak experiments, electron density of the order 1019–21 m−3 had been measured in the flux conserver region, but no density measurement had been reported for...

We have studied the parsec-scale structure of The images show an unresolved " core " and a radio jet extending over distances up to 25 milliarcseconds. At 1.3 and 2 cm, images of the linearly polarized emission reveal an alignment of the electric vector with the extremely curved inner section of the jet. At 6 cm, the jet shows strong fractional polarization (m∼15%), with the electric vector bei...

We study the tomographic applications of a new phenomenon we dub "jet drift" -- deflection high-energy particles and jets toward direction flowing medium to quark-gluon plasma produced in heavy-ion collisions. While physics jet drift is quite general, for specificity consider case photon-jet production at mid-rapidity. Beginning with simplest possible model, large slab uniformly plasma, systema...
