论文摘要
我们研究了Weldenstein 7-X恒星剂的不同磁性构型中湍流转运的影响。特别是，我们使用全局陀螺仪代码基因-3D进行了直接的数值模拟，对W7-X的标准，高晶格和低晶格构型中离子温度梯度湍流的行为进行了建模。我们发现，低肌配置比高摩尔和标准配置产生的传输更多。通过与径向局部模拟进行比较，我们证明了执行全局非线性模拟以定量预测湍流的重要性。
We study the effect of turbulent transport in different magnetic configurations of the Weldenstein 7-X stellarator. In particular, we performed direct numerical simulations with the global gyrokinetic code GENE-3D, modeling the behavior of Ion Temperature Gradient turbulence in the Standard, High-Mirror, and Low-Mirror configurations of W7-X. We found that the Low-Mirror configuration produces more transport than both the High-Mirror and the Standard configurations. By comparison with radially local simulations, we have demonstrated the importance of performing global nonlinear simulations to predict the turbulent fluxes quantitatively.
