论文摘要
在恒星剂中，纬向流动活性通过未完全理解的机制相互作用敏感地取决于三维磁场的几何形状。在这项工作中，我们通过研究Wendelstein 7-X Stellarator的三种磁性构型来调查这一点。我们发现线性纬向流阻尼的变化伴随着非线性驱动器的变化，并识别控制这些效果的关键几何特征。了解所得平衡对于开发减少湍流传输模型很重要。
In stellarators, zonal flow activity depends sensitively on geometry of the three dimensional magnetic field, via an interplay of mechanisms that is not fully understood. In this work, we investigate this by studying three magnetic configurations of the Wendelstein 7-X stellarator. We find that variation in linear zonal flow damping is accompanied by variation in nonlinear drive, and identify key geometric features that control these effects. Understanding the resulting balance is important for the development of reduced models of turbulent transport.
