摘要/Abstract

摘要： 通过统一二维直角坐标与柱坐标下三温能量方程的差分格式,实现了LARED-H (laser radiation electron dynamic holehurm)程序既可以模拟正入射激光平面靶过程,也可模拟斜入射平面靶问题,从而扩展了LARED-H程序的功能.使用发展后的LARED-H程序进行了直角坐标系下线聚焦打靶耦合过程数值模拟,给出了不同入射角度下靶等离子体的膨胀过程.

关键词: 二维三温能量方程, 平面坐标与柱坐标, 平面靶数值模拟

Abstract: A difference scheme for two-dimensional three-temperature energy equations in Cartesian coordinates is united with that in cylindrical coordinates.The LARED-H (laser radiation electron dynamic holehurm) code is extended to describe physical processes in both coordinates.Physical models are investigated for a line-focused target with different incident angles.Numerical results are given to describe the expanding process of target-plasma.

Key words: two-dimensional three-temperature energy equation, Cartesian coordination, cylinder coordination, planar target
