有限离子温度等离子体中的ExB平均流

ExB mean flows in finite ion temperature plasmas

J. Madsen, J. Juul Rasmussen, V. Naulin, A. H. Nielsen

摘要:

研究了离子压力动力学对E x B平均流的影响。使用一个简化的,二维的,漂移有序的流体模型在薄层近似,三个应力,除了雷诺应力被示出修改E × B平均流量。应力张量中的这些附加项都需要离子压力波动。准线性分析表明,这些额外的应力是一样重要的雷诺应力,因此必须考虑到在分析中剪切E x B平均流量的关键成分的运输障碍。

英文摘要:

The impact of ion pressure dynamics on E x B mean flows is investigated. Using a simplified, two-dimensional, drift ordered fluid model in the thin-layer approximation, three stresses in addition to the Reynolds stress are shown to modify the E x B mean flow. These additional terms in the stress tensor all require ion pressure fluctuations. Quasi-linear analysis show that these additional stresses are as important as the Reynolds stress, and hence must be taken into account in analysis of transport barriers in which sheared E x B mean flows are key ingredients.
