  • Abstract
    CFD simulations of electric arcs in circuit breakers require physically reliable and computationally treatable models for the complex physics involved. This article discusses two entropy-production based concepts for radiation and nozzle ablation modeling with improved balance between physical foundation and needed computational resources.
