Numerical analysis of cold core formation during wire electroexplosion

It has been shown experimentally that wire explosion is connected with cold core formation and leads to a complex profile of magnetic field [1, 2]. The focus of the paper is the attempt to analyze this phenomena by numerical modelling. A series of calculations has been carried out using 1D radiation Lagrangian MHD code ERA [3]. The model has been developed and the influence of different terms including into the model has been analyzed.
