Thermal fluid analysis of metal vapor is important because metal vapor generated during the High Energy Arcing Faults (HEAF) has significant thermal damage to its surroundings. In this study, the analysis that includes the energy balance was conducted in order to consider in detail the effect of radiation by HEAF explosion.
