论文摘要
通过Biermann电池机制自我生成的磁场增强了非线性消融雷利 - 泰勒（RT）的不稳定性的增长率。提出了对这种效果的缩放，并通过扩展的杂种水动力模拟进行了扰动高度和波长的缩放。发现单个RT尖峰周围的磁通量产生速率随尖峰高度扩展。量化电子磁化的霍尔参数因峰值尖端处的磁场的Nernst压缩而发现短波长尖峰的强烈增强。磁场对尖峰生长的影响是通过抑制的热传导到不稳定的尖峰中，而righi-leduc热流则从尖峰尖端偏转了热量。发现Righi-leduc是小霍尔参数的主要效果，而被抑制的热传导占主导地位的大厅参数。这些结果证明了在所有扰动惯性限制融合热点中考虑磁场的重要性。
The growth rate of the non-linear ablative Rayleigh-Taylor (RT) instability is enhanced by magnetic fields self-generated by the Biermann battery mechanism; a scaling for this effect with perturbation height and wavelength is proposed and validated with extended-magnetohydrodynamic simulations. The magnetic flux generation rate around a single RT spike is found to scale with the spike height. The Hall Parameter, which quantifies electron magnetization, is found to be strongly enhanced for short wavelength spikes due to Nernst compression of the magnetic field at the spike tip. The impact of the magnetic field on spike growth is through both the suppressed thermal conduction into the unstable spike and the Righi-Leduc heat-flow deflecting heat from the spike tip to the base. Righi-Leduc is found to be the dominant effect for small Hall Parameters, while suppressed thermal conduction dominates for large Hall Parameters. These results demonstrate the importance of considering magnetic fields in all perturbed inertial confinement fusion hot-spots.
