【摘要】：在一维内爆磁流体力学编码MC11D的基础上,引入了解析形式的状态方程组。利用改造后的编码对样品为铜材料的柱面内爆磁通量压缩实验进行了模拟,得到了样品管内壁的速度历史,材料的p-V关系曲线以及温升曲线。与原编码利用列表式状态方程数据库计算的结果比较,由两种状态方程模拟得到的速度曲线符合程度很好,所得p-V曲线的最大相对偏差为6.6%,温升曲线基本吻合,且模拟的速度曲线与实验结果符合较好。通过对MC11D编码的改造,拓展了其应用范围,使其可对未包含于现有列表式状态方程数据库中的材料进行模拟,为实验结果分析及数据处理提供了一种方法。
[Abstract]:On the basis of one-dimensional implosion MHD coding MC11D, the analytic state equations are introduced. The compression experiment of cylindrical implosion flux of copper material was simulated by the modified code. The velocity history of the inner wall of the sample tube, the p-V relation curve and the temperature rise curve of the sample tube were obtained. Compared with the results obtained by the original code using the tabular equation of state database, the velocity curves simulated by the two state equations are in good agreement with each other. The maximum relative deviation of the p-V curves is 6.6, and the temperature rise curves are in good agreement with each other. The simulated velocity curve is in good agreement with the experimental results. Through the modification of MC11D coding, its application scope is extended to simulate the materials not included in the existing tabular equation of state database, which provides a method for the analysis of experimental results and data processing.
