We present the breaking of a short-circuit current in a HBC fuse simulation based on an isentropic non stationary model in a porous medium for a one dimensional geometry. The fluid flow is affected by the nature of the gas and by the morphology of the silica sand. Numerical simulations with realistic physical parameters have been performed using a finite volume scheme with a fractional step technique.
