electric arc
The mechanism of conducting-gas acceleration in an electric arc by intrinsic magnetic field was first investigated in [1].
      
The present work proposes a modified version of the difference method [4] and a series of integral methods for the calculation of the conducting-gas flow in a high-current electric arc.
      
Development of the temperature fields in an electric arc struck on a point electrode in a homogeneous gas stream
      
The development of an electric arc struck on a point cathode in a medium which moves without deformation is studied.
      
The stationary problem of a two-dimensional electric arc that develops in a medium with piecewise constant electrical conductivity is solved.
      
In an investigation of the flow of hightemperature gas, in which an electric arc heater was used to supply the thermal energy, the profiles of the total pressure and the stagnation temperature were measured at different sections of the channel.
      
Experimental Investigation of the Interaction between an Electric Arc and a Gas Flow
      
The model describes a two-phase (coal particles + air) chemically reacting flow, which propagates in a channel with or without an internal heat source (an electric arc, a plasmatron torch, or exothermic chemical reactions).
      
Numerical simulation is used to investigate the interaction between laser radiation and the plasma of welding electric arc.
      
Analysis of open-flame electric arc in transverse magnetic field
      
The paper is concerned with substantiating a high metrological "quality" of the cathode section of a stationary electric arc in plasma generators which have a current density of over 2 kA/cm2, a diverging anode channel, and vortex stabilization.
      
The results of this comparison further lead one to conclude that a low-current electric arc is an arc with liquid cathode and anode spots, and that the melting process is a stabilizing factor as regards the current density in those spots.
      
Numerical Simulation of Gasdynamic Flows Formed by an Electric Arc in an External Transverse Magnetic Field
      
The results of numerical investigations of an electric arc in an external transverse magnetic field are given.
      
Some singularities of the flow formed by an electric arc in an external transverse magnetic field are revealed.
      
Calculation of Laminar Flows of Plasma in the Channel of a Plasmatron with the Self-Adjusting Length of the Electric Arc
      
A new analytical solution of the Elenbaas-Heller equation is derived, which generalizes the channel model of electric arc to the case when the volume radiation makes a significant contribution to the electric arc energy balance.
      
In determining the arc length, it is assumed that the electric arc is shifted downstream of the flow and, at the same time, performs random walks over the channel cross section.
      
Calculation of Electric Arc in Longitudinal Magnetic Field
      
A steady-state three-dimensional mathematical model is used to calculate an electric arc in an external longitudinal magnetic field.
