Abstract :
Scalar and vector magnetic formulations have been applied to solve the current distribution in a 50 Hz direct resistance heating system of ferromagnetic tubes. The scalar formulation driven via an external circuit has been also applied to solve the Time-Harmonic EM part of the problem coupled with the thermal transient: the computed warm up curves have been compared with experimental data.
