Accounting for Radiation in the Simulation of Electrical Explosion of Conductors

The mathematical models used to describe the processes involved in an electrical explosion of conductors are traditionally based on the magnetohydrodynamic approximation. To perform numerical calculations in this approximation requires preliminary knowledge of the equations of state of the conductor material in different phases for a wide range of thermodynamic parameters and corresponding transport coefficients. In solving problems related to the study of dense plasmas, it is of critical importance to characterize the plasma self-radiation in order to estimate the radiation losses and determine the spectral characteristics of the radiation for diagnostic purposes. There is a great variety of methods to characterize the self-radiation of plasmas. In this paper, we present a comparative analysis of different methods for calculating the characteristics of a dense plasma for which the conditions for thermodynamic equilibrium are satisfied.
