摘要: 探讨了Z箍缩等离子体辐射磁流体模拟二维三温物理模型及其数值计算方法,针对“强光一号”加速器上Kr喷气实验的具体条件,利用辐射磁流体力学程序Z-pinch 2D-DG模拟了Kr喷气等离子体聚爆过程,分析了X射线辐射的特点,给出了等离子体密度和温度的演化图像以及喷气箍缩中一些带有普遍性的结论。Abstract: This paper presents a twodimensional threetemperature physical model of Zpinch plasmas and its numerical methods. A twodimensional radiation magnetohydrodynamics code called Zpinch2DDG is developed, which numerically simulates Kr gaspuff plasma implosion based up on the real experimental parameters on the Qiang Guang1 generator. The evolutional pictures of the plasma density and temperature are given, and Xray radiation is analyzed physically. As a result, some universal conclusions about gaspuff implosion are summarized.
