Sheath parameters for non-Debye plasmas: simulations and arc damage [PDF]
, 2012 This paper describes the surface environment of the dense plasma arcs that damage rf accelerators, tokamaks and other high gradient structures. We simulate the dense, non-ideal plasma sheath near a metallic surface using Molecular Dynamics (MD) to ...

Numerical simulations of arc plasma under external magnetic field-assisted gas metal arc welding
AIP Advances, 2020 The arc plasma behavior for gas metal arc welding (GMAW) with an external compound magnetic field was numerically investigated. A three-dimensional finite element model for the external magnetic field (EMF) and a three-dimensional finite volume model for

Arc Plasma Propagation and Arc Current Profiles [PDF]
IEEE Transactions on Plasma Science, 2019 When electrical arcs occur in space, a plasma expands away from the arc-site, neutralizing adjacent surfaces (a current), and causing a current to be produced at the arc-site (source of neutralization current). The speed of this plasma expansion depends on the plasma species, which in turn depend on the ionizable materials near the initial ...
