磁化等离子体中的二维turbulence

Two-dimensional turbulence in magnetised plasmas

Alexander Kendl

摘要:

在非均匀磁化等离子体中,能量和粒子垂直于磁场的输运一般主要由准二维湍流混合引起。湍流和结构形成的物理学对于实验或工业应用中的每一个磁约束实验室等离子体都具有普遍的重要性。具体而言,用于聚变能研究的高温等离子体也由这种湍流输运的性质主导。自组织的湍流涡旋的介观结构,如带状流是有关的传输障碍,可以显着提高约束的聚变等离子体的形成。在等离子体物理或连续介质动力学的入门课程中,很少涉及这个在研究中非常重要的课题。在这里,一个简短的教程二维流体和等离子体湍流介绍了该领域,适合列入本科和研究生课程。

英文摘要:

In an inhomogeneous magnetised plasma the transport of energy and particles perpendicular to the magnetic field is in general mainly caused by quasi two-dimensional turbulent fluid mixing. The physics of turbulence and structure formation is of ubiquitous importance to every magnetically confined laboratory plasma for experimental or industrial application. Specifically, high temperature plasmas for fusion energy research are also dominated by the properties of this turbulent transport. Self-organisation of turbulent vortices to mesoscopic structures like zonal flows is related to the formation of transport barriers that can significantly enhance the confinement of a fusion plasma. This subject of great importance in research is rarely touched on in introductory plasma physics or continuum dynamics courses. Here a brief tutorial on 2D fluid and plasma turbulence is presented as an introduction to the field, appropriate for inclusion in undergraduate and graduate courses.
