要約(英語): Three-dimensional and time-dependent numerical analysis is carried out to understand the behavior of SF6 arc plasma under an externally applied magnetic field and to clarify the influence of the applied magnetic field on the electrical resistance of arc plasma and the pressure in a simple chamber. Numerical analysis takes into account the radiative heat loss, the Lorentz force, the Joule heating, and variations of thermodynamic properties and transport coefficients of SF6. Numerical results show that the arc plasma rotates and the length of arc column increases by the Lorentz force. The electrical resistance of arc plasma is increased by applying the magnetic field because of the following two factors: the increase in the length of arc column and the promotion of heat transfer attributed to the rotation of arc plasma. The promotion of heat transfer also causes an increase in the pressure in the chamber.
