We present the results of the first Charged-Particle Transport Coefficient Code Comparison Workshop, which was held in Albuquerque, NM October 4–6, 2016. In this first workshop, scientists from eight institutions and four countries gathered to compare calculations of transport coefficients including thermal and electrical conduction, electron–ion coupling, inter-ion diffusion, ion viscosity, and charged particle stopping powers. Here, we give general background on Coulomb coupling and computational expense, review where some transport coefficients appear in hydrodynamic equations, and present the submitted data. Large variations are found when either the relevant Coulomb coupling parameter is large or computational expense causes difficulties. Understanding the general accuracy and uncertainty associated with such transport coefficients is important for quantifying errors in hydrodynamic simulations of inertial confinement fusion and high-energy density experiments.

我们介绍了2016年10月4日至6日在新墨西哥州阿尔伯克基举行的首个带电粒子传输系数代码比较研讨会的结果。在此首次研讨会中，来自八个机构和四个国家的科学家聚集在一起，比较了包括导热和导电，电子-离子耦合，离子间扩散，离子粘度和带电粒子阻止能力。在这里，我们给出了库仑耦合和计算费用的一般背景，回顾了流体动力学方程中出现的某些输运系数，并给出了提交的数据。当相关的库仑耦合参数较大或计算费用引起困难时，会发现较大的变化。
