Original Abstract

A numerical model of an electric arc based on Magnetohydrodynamics Theory was investigated, adjusted and implemented as a user-defined model into ANSYS FLUENT. The goal of this model was to simultaneously calculate electric and magnetic fields, which is not possible with built-in ANSYS MHD model. This custom model was then applied on a problem which described opening of contacts between which an electric arc was created. The development of the arc was investigated by its temperature field. A comparison of built-in and presented model was carried out.
