The role of flux-limited thermal conduction on the fusion performance of the uniaxially driven targets studied by Derentowicz et al. [J. Tech. Phys. 18, 465 (1977) and J. Tech. Phys. 25, 135 (1977)] is explored as part of a wider effort to understand and quantify uncertainties in inertial confinement fusion (ICF) systems sharing similarities with First Light Fusion's projectile-driven concept. We examine the role of uncertainties in plasma microphysics and different choices for the numerical implementation of the conduction operator on simple metrics encapsulating the target performance. The results indicate that choices that affect the description of ionic heat flow between the heated fusion fuel and the gold anvil used to contain it are the most important. The electronic contribution is found to be robustly described by local diffusion. The sensitivities found suggest a prevalent role for quasi-nonlocal ionic transport, especially in the treatment of conduction across material interfaces with strong gradients in temperature and conductivity. We note that none of the simulations produce neutron yields that substantiate those reported by Derentowicz et al. [J. Tech. Phys. 25, 135 (1977)], leaving open future studies aimed at more fully understanding this class of ICF systems.

单轴驱动聚变目标对通量受限热传导建模敏感性的初步评估

Derentowicz等人研究的通量限制热传导对单轴驱动目标聚变性能的作用。[J. 技术。物理。18 , 465 (1977) 和 J. Tech。物理。25, 135 (1977)] 作为更广泛努力的一部分进行探索，以了解和量化惯性约束聚变 (ICF) 系统中的不确定性，该系统与 First Light Fusion 的弹丸驱动概念有相似之处。我们研究了不确定性在等离子体微物理中的作用以及传导算子在封装目标性能的简单指标上的数值实现的不同选择。结果表明，影响加热聚变燃料和用于容纳它的金砧之间的离子热流描述的选择是最重要的。发现电子贡献被局部扩散有力地描述。发现的敏感性表明准非局部离子传输的普遍作用，尤其是在处理温度和电导率具有强梯度的材料界面的传导方面。我们注意到没有一个模拟产生证实德伦托维奇报告的中子产额等。[J. 技术。物理。25 , 135 (1977)]，留下开放的未来研究，旨在更全面地了解此类 ICF 系统。
