Abstract:The initial stage of explosion of a thin tungsten wire by a high-power current pulse of nanosecond duration is simulated. Radial distributions of parameters of matter are obtained for two models. According to one of the models, it is assumed that an instantaneous separation into phases occurs if the parameters of metal have reached values corresponding to the binodal; in the other model, the existence of a metastable state is allowed. Phase trajectories in the P–Tand ρ–Tplanes are given.
