论文摘要
我们构建了一个托卡马克设备X点附近的湍流的模型，在合适的假设下，我们到达了电场电位波动的封闭方程。分析和数值分析集中在减少的动力学的二维公式上，这允许直接映射到不可压缩的Navier-Stokes方程。这项研究的主要优点是概述X点附近的湍流如何与中尺寸和大尺寸tokamaks的典型操作条件相对应，以从大到较小的空间尺度的Enstrophy Cascade主导。
We construct a model for the turbulence near the X-point of a Tokamak device and, under suitable assumptions, we arrive to a closed equation for the electric field potential fluctuations. The analytical and numerical analysis is focused on a reduced two-dimensional formulation of the dynamics, which allows a direct mapping to the incompressible Navier-Stokes equation. The main merit of this study is to outline how the turbulence near the X-point, in correspondence to typical operation conditions of medium and large size Tokamaks, is dominated by the enstrophy cascade from large to smaller spatial scales.
