Method of Magnetic Simulation Applied to Gliding Arc Diagnostics

In this paper, it was proposed using a magnetic diagnostic method, to determine the variation of the length and the dynamic of gliding arc. This method, which is not intrusive, uses the hypothesis that the plasma and the reactor elements are similar to threadlike current segments. The magnetic induction created by the plasma and the circuit elements is measured in different sites outside of the reactor. To estimate the plasma shape and position, the measured magnetic inductions is compared to the one calculated using Biot-Savart law.
