| Abstract | The model is developed of near-cathode layers in high-pressure arc discharges. Governing equations include equations of conservation of the ions, the atoms, and the electrons, transport equations for the ions, the atoms, and the electrons, equations of energy for the electrons and the heavy particles, and the Poisson equation. The equations are solved numerically in 1D without any further simplifications, in particular, without explicitly dividing the near-cathode layer into a space-charge sheath and quasi-neutral plasma. Results of numerical simulation of the layer in atmospheric-pressure argon arc with tungsten cathode are given: distributions of plasma parameters across the layer, current-voltage characteristics, energy flux from the plasma to the cathode. The results are compared with those obtained in the framework of an approximate approach. 1. |
