An investigation of a vortex stabilized arc

University of British Columbia

The power balance equations for the column of a 500 A DC vortex stabilized arc in argon have been solved numerically to give predicted values for the temperature profile, radiative power and heat transport to the wall. These quantities have also been measured using spectroscopy and calorimetry, and compared with the theoretical results so as to refine our understanding of the heat transport processes in the arc. Further study is required to predict convective effects accurately, especially at low power levels, but the results show that the behaviour of the column is predictable at high power levels. Forced convection has been shown to play an important role in the arc column.
