Process of radiation magnetohydrodynamics in Al wire-array Z-pinch

The equations of one-dimensional three-temperature radiation magnetohydrodynamics, which are to describe the plasma process of Z-pinch, were set up under Largrangian coordinates. The Al wire-array Z-pinch experiment on Saturn in Sandia laboratory in USA, was simulated using authors' one-dimensional Lagrangian code based on the equations. The reasonable and self-consistent spatiotemporal distributions of all plasma parameters in the process were obtained. The time and velocity of Z-pinch plasma to center, pulse width and energy of X-ray radiated by the Z-pinch plasma are basically agreed with the experimental results on Saturn. The results suggested that the equations and its code are correct
