| Abstract: | This paper presents a two dimensional three temperature physical model of Z pinch plasmas and its numerical methods. A two dimensional radiation magneto hydrodynamics code called Z pinch2D DG is developed, which numerically simulates Kr gas puff plasma implosion based up on the real experimental parameters on the Qiang Guang 1 generator. The evolutional pictures of the plasma density and temperature are given, and X ray radiation is analyzed physically. As a result, some universal conclusions about gas puff implosion are summarized. |
