Numerical simulation of tungsten wire-array pinch plasma

A two-dimensional, three-temperature radiation magneto-hydrodynamics model is applied to the simulation of tungsten wire-array plasma implosion based on the real experimental parameters of the Qiangguang-1 generator. The spatial-temporal evolutions of the plasma density and temperature are presented, and the characteristic of the magnetic field and current density is analyzed and summarized. The calculated X-ray power curve is approximately in agreement with the corresponding measured one. All these predicted quantities are conducive to the plasma diagnoses of Z-pinches. In addition, some of physical parameters and numerical schemes related to this simulation are discussed also.
