Author(s): 
Pages: 667-672
Year: Issue:  6
Journal: CHINESE JOURNAL OF COMPUTATIONAL PHYSICS

Keyword:  有限差分数值模拟激光支持等离子体;
Abstract: 采用单流体模型描述由强激光产生的烧蚀等离子体,并用具有五阶精度的广义Godunov差分格式--加权本质无振荡格式对该模型进行离散化,考虑激光与等离子体相互作用和能量耦合,数值模拟强激光与固体靶相互作用时产生的烧蚀等离子体随时间演化的物理过程,给出数值模拟结果,并对其进行分析和讨论.数值模拟结果表明,激光能量在靶面等离子体中被强烈吸收,激光支持LSD(Laser Supported Detonation)波速度约为理想LSD波速度的一半.
