  • Abstract
    Plasma torches are involved in many industrial processes, but plasma jet instabilities reduce the reproducibility and the efficiency of processes in which they are involved. In this current work, a setup has been developed to visualize the arc attachment at the anode. It allows to simulate the effect of cold boundary layer on the arc attachment in conditions similar to those encountered in direct current (dc) plasma spray torches.
