A free-burning electric arc subjected to a cross-flow and a cross magnetic field is represented by an impermeable fluid cylinder model. This model allows for both momentum and energy exchange processes by viscous forces and conductive heat transfer around the cylindrical surface. Convective effects through the surface are assumed not to occur. The fluid dynamic and heat transfer characteristics within and outside the fluid cylinder model are investigated by proper matching of both flow and temperature fields at the cylinder boundary. The study shows that the arc radius and centerline temperature can be calculated provided the magnitudes of the applied external fields are known. The external fields are the electric field, the magnetic field and the cross flow field. The relationship among these parameters for a nitrogen arc is shown graphically. Author
