托克马克中环形angular momentum湍流输运的上下对称性

Up-down symmetry of the turbulent transport of toroidal angular momentum in tokamaks

Felix I. Parra, Michael Barnes, Arthur G. Peeters

摘要:

本文给出了托卡马克装置中高流量区局部非线性δ-f回旋动力学方程组的两种对称性。环向角动量的湍流输运在托卡马克的上下反射以及旋转和旋转剪切的符号变化下改变符号。因此,在没有旋转和旋转剪切的情况下,上下对称托卡马克的环形角动量的湍流输运必然为零。这对自发旋转的建模具有重要意义。

英文摘要:

Two symmetries of the local nonlinear delta-f gyrokinetic system of equations in tokamaks in the high flow regime are presented. The turbulent transport of toroidal angular momentum changes sign under an up-down reflection of the tokamak and a sign change of both the rotation and the rotation shear. Thus, the turbulent transport of toroidal angular momentum must vanish for up-down symmetric tokamaks in the absence of both rotation and rotation shear. This has important implications for the modeling of spontaneous rotation.
