要确定托卡马克的内禀旋转分布,需要有环面角动量的径向通量。它的计算需要知道陀螺动力学分布函数和二阶湍流静电势,其中ρ为离子拉莫尔半径,L为磁场的变化长度。本文给出了计算任意托卡马克环面角动量径向输运的完整方程组。特别是,首次给出了分布函数和静电势的湍流分量的0 (ϵ2)方程,而不假设极向磁场比磁场强度小。
The radial flux of toroidal angular momentum is needed to determine tokamak intrinsic rotation profiles. Its computation requires knowledge of the gyrokinetic distribution functions and turbulent electrostatic potential to second-order in ϵ = ρ/L, where ρ is the ion Larmor radius and L is the variation length of the magnetic field. In this article, a complete set of equations to calculate the radial transport of toroidal angular momentum in any tokamak is presented. In particular, the O(ϵ2) equations for the turbulent components of the distribution functions and electrostatic potential are given for the first time without assuming that the poloidal magnetic field over the magnetic field strength is small.
