铝丝阵列Z箍缩的辐射磁流体动力学过程

在拉格朗日坐标系下，建立了描述Z箍缩等离子体内爆动力学过程的一维三温辐射磁流体力学方程组，并编制了相应的拉氏程序。利用该程序对美国Sandia实验室Saturn装置上的铝丝阵列内爆实验进行了数值模拟，得到了内爆等离子体各参量的时空分布。其中内爆到心时刻、X光峰值功率、X光总能量等计算结果与实验结果基本一致。表明所建立的物理模型和编制的程序是合理和可靠的。

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 our 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.
