要約(英語): Arcs are used in a wide range of fields such as welding, circuit breakers, and waste treatment. It is required to clarify the dynamic behavior of the arc and the physical phenomena of the cathode spot and the anode spot in order to improve the performance of products related to the arc phenomenon. Thus, the physical phenomenon of arc has been elucidated from both experiments and numerical analysis. However, few reports have considered the asymmetry and non-equilibrium. In this paper, the arc electron and heavy particle temperature distribution were analyzed with the lateral flow velocity for elucidation of re-strike. As a result, the heavy particle temperature increased in the cold boundary layer under consideration of thermal non-equilibrium. Therefore, it was suggested that the factor of re-strike is the increase in heavy particle temperature.
