Abstract :
The heat transfer and plasma flow inside an argon arc exposed in an axial magnetic field (AMF) at atmospheric pressure are simulated with an axisymmetric-swirl model. The numerical results show that the AMF induces most of the plasma flowing by the arc mantel, and as a result, the AMF arc presents a hollow bell shape.
