Numerical Magnetohydrodynamic Simulation of Z-pinch Experiment Shot 51 on Z-machine using 2D Eulerian Code FLUX-RZ

Summary form only given. The paper presents simulation results of a Z-pinch experiment shot 51 using numerical code FLUX-rz, developed in STCP RFNC-VNIIEF. Calculations of an implosion process of a tungsten liner load were carried out with stationary uniform Eulerian grid in frameworks of a two-dimensional (in r-z plane) radiation magnetic hydrodynamics at self-consistent consideration of equations of the Z-machine electrical circuit. In the result of the performed numerical research we revealed a significant dependence of obtained results, a pulse of a generated radiation in particular, on artificially set values of an electric conductivity in low-density "pseudo-vacuum" areas of the pinch plasma.
