中文简介: | 本课程描述了质量,动量和能量在等离子体中传输的过程,特别是磁约束聚变应用。 Fokker-Planck碰撞算子及其限制形式,以及碰撞松弛和平衡,都被详细考虑。特殊应用包括洛伦兹气体,布朗运动,α粒子和失控电子。提出了基于Fokker-Planck方程的一般几何中经典碰撞传输的Braginskii公式。托卡马克中的新古典运输,其对磁几何的细节敏感,被认为是高(Pfirsch-Schluter),低(香蕉)和中间(高原)碰撞机制。 |
课程简介: | This course describes the processes by which mass, momentum, and energy are transported in plasmas, with special reference to magnetic confinement fusion applications. The Fokker-Planck collision operator and its limiting forms, as well as collisional relaxation and equilibrium, are considered in detail. Special applications include a Lorentz gas, Brownian motion, alpha particles, and runaway electrons. The Braginskii formulation of classical collisional transport in general geometry based on the Fokker-Planck equation is presented. Neoclassical transport in tokamaks, which is sensitive to the details of the magnetic geometry, is considered in the high (Pfirsch-Schluter), low (banana) and intermediate (plateau) regimes of collisionality. |
