A 2D (r-z) and 2-temperature (T{sub e,i}) nonideal MHD numerical model of dense Z-pinch dynamics and its applications to exploded wire plasmas with a cold dense core are presented. The numerical simulation algorithm is based on an Eulerian-Lagrangian method that is related to one suggested by D'yachenko for hydrodynamic calculations. As expected, a high density core that appears in the initial stage of the electrical explosion of a metal wire is found to be colder than the surrounding plasma. Model results are in good agreement with experimental data for exploded wires in a high current nanosecond diode.
