| 摘 要： | 任意拉格朗日欧拉方法被认为是解决2维流体力学大变形数值模拟的有效途径之一。以激光黑腔靶耦合问题为背景，结合质量流的物理意义，提出了一种二阶守恒物理量重映的算法，并利用1维激光靶耦合程序对方法及其可行性进行了考察，结合物理问题调整网格，用较少的网格得到了与较多网格拉氏计算同样的结果。为算法在2维LARED-H程序中的应用奠定了基础。

| Abstract: | In 2D hydrodynamic simulation, Lagrangian mesh are prone to distort. The ALE (Arbitrary Lagrangian-Eulerian) method which combines the best features of Lagrangian and Eulerian representation was widely used to solve large distortion problems. Based on laser-target coupling, a new second order conservative remapping algorithm for physical variables utilizing mass flux was developed. In this paper, the new algorithm is applied in 1D laser-target code and has satisfactory results in practical model simulations. |
