摘要:
通过量子分子动力学(QMD)模拟(密度高达600 g/cm $^{3}$和$10^{4}$ eV的温度)的状态方程的一致的描述,和有关氘-氚混合物的输运系数的信息被证明。扩散系数和粘度进行了比较与一个组件等离子体模型在不同的制度,从强耦合的动力学。电子和辐射输运系数,这是比较目前使用的模型在流体动力学模拟的惯性约束聚变,评估高达800 eV。从高简并区到中间区,讨论了洛仑兹数。
英文摘要:
Consistent descriptions of the equation of states, and information about transport coefficients of deuterium-tritium mixture are demonstrated through quantum molecular dynamic (QMD) simulations (up to a density of 600 g/cm$^{3}$ and a temperature of $10^{4}$ eV). Diffusion coefficients and viscosity are compared with one component plasma model in different regimes from the strong coupled to the kinetic one. Electronic and radiative transport coefficients, which are compared with models currently used in hydrodynamic simulations of inertial confinement fusion, are evaluated up to 800 eV. The Lorentz number is also discussed from the highly degenerate to the intermediate region.
