摘要

The high-intensity free-burning arc is modeled using a computational domain including the arc itself and the arc cathode and anode. It is shown that the energy equation with the temperature, instead of the specific enthalpy, as the dependent variable has to be used in order to obtain physically reasonable heat fluxes from the plasma to the electrodes if a SIMPLE-like algorithm is employed in the modeling.
