AbstractElectrode ablation is a key factor that affects the life and performance of the direct current arc plasma generator, which is closely related to the near-electrode behavior of the arc. Compared with the constricted-type arc root, diffused-type arc root is more conducive to reduced thermal load, thereby improving the electrode life and the discharge stability. The attachment behavior of the arc root is related to the transport properties of the arc near the electrode wall and the aerodynamic and electromagnetic forces on the root of the arc. From this point of view, aerodynamical dispersion of the arc root using a converging-diverging nozzle was proposed, and the key factors that affect the dispersion were analyzed and verified.
