激光与金靶耦合中非局域电子热传导的影响
-
摘要: 在一维非平衡辐射流体力学程序中，引入非局域电子热传导公式，对三倍频激光与金平面靶耦合产生等离子体状态进行了数值模拟计算。数值结果与加限流处理的Spitzer-Harm公式计算结果的比较表明，非局域电子热传导能够得到更为合理的数值结果和物理图象。Abstract: The nonlocal heat conduction for electrons is introduced into one-dimensional non-LTE radiation hydrodynamic code and usedto the simulation of 0.35m m laser-Au target coupling. The comparison of the numerical results shows that , compared to the flux-limited Spitzer-Harm formula , the simulation with taking account of nonlocal electron conductivity is more reasonable.
