Abstract
The motion of an arc discharge in an external transverse magnetic field has been investigated experimentally and numerically. Two-dimensional modeling was carried out within the framework of the magnetoplasmadynamic approximation in the programs PLASMAERO and Comsol Multiphysics 5.3. A comparison of the calculation results with the experimental data shows a qualitative agreement between the observed temperature and velocity fields for both cases. At the same time, it was shown that the difference in the numerical approaches, used in either package, for a given problem leads to a significant difference in quantitative characteristics, such as arc diameter, peak temperature and arc channel velocity.
