离子温度梯度 turbulence 数据集
收藏资源简介:
该数据集由美国马里兰大学电子与应用物理学研究所等机构的研究人员创建,包含超过20万次非线性模拟的离子温度梯度 turbulence 在不同非轴对称几何形态下的结果。数据集通过优化和随机生成的恒星器平衡态生成。在固定梯度和其他输入参数下,不同几何形态之间的湍流热通量可能相差几个数量级。该数据集可用于测试其他提出的 turbulence 代理模型,并已与本文一起公开发布,以供其他研究人员使用。
This dataset was created by researchers from the Institute of Electronics and Applied Physics at the University of Maryland, USA, and other institutions. It contains results from more than 200,000 nonlinear simulations of ion temperature gradient turbulence under various non-axisymmetric geometric configurations. The dataset is generated using optimized and randomly generated stellarator equilibrium states. Under fixed gradient and other input parameters, turbulent heat fluxes can differ by several orders of magnitude across different geometric configurations. This dataset can be used to test other proposed turbulence surrogate models, and has been publicly released alongside this paper for use by other researchers.
