Calculation of the thermal interaction between an arc column and the electrodes
- 16 Downloads
The temperature distribution in an arc column of finite length is treated as a two-dimensional nonlinear boundary-value problem with the cooling effect of the electrodes taken into account. The sharp temperature drop near the electrodes is represented by a thermal boundary layer of the arc, without explicitly considering the structure of the zones adjacent to the electrodes. The temperature, the thermal fluxes into the electrodes, and the field intensity as well as the voltage in the arc are calculated.
