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。
In the one-dimensional unbalanced radiation hydrodynamics program, a non-local electronic heat conduction formula is introduced to simulate the plasma state generated by the coupling between the triplet laser and the gold planar target. Comparison of the numerical results with those of the Spitzer-Harm formula with the current-limited treatment shows that the non-local electronic heat conduction can obtain more reasonable numerical results and physical images.
