Abstract
Electrical arcs in circuit breakers are very complex phenomena involvi ng many aspects of Physics: fluid mechanics, radiative processes, elec tromagnetics... and their numerical modelling exhibits various couplin gs. After a physical analysis of the phenomena, showing which coupling s are important and which are not, we present axisymmetric simulations of arcs for two kinds of SF6 breakers, a two pressure breaker and a r otary arc breaker. We focus our study on the coupling between fluid me chanics and electromagnetics (influence of Laplace forces on the flow, stability).
