Experimental validation of MHD arc simulation in encapsulated horn gap arrangements

This work describes the use of experimental methods on model spark gaps for comparison with the simulation models (MHD) from the ignition of the impulse arc to the entry of the arc into the arc chamber, taking into account material effects and thermal reignitions of the arc, e.g. as a result of the gas flow within the encapsulated spark gap. Examples are provided to show that the simulation can accurately represent the experimental processes and improve the understanding of the complex processes.
