漂移波-纬向流动力学

Drift wave-zonal flow dynamics

Brian F. Farrell, Petros J. Ioannou

摘要:

在湍流中,一个显著的现象是自发出现空间尺度的大尺度带状射流。这种现象的地球物理学例子包括木星带状风和地球的极锋喷流。在这项工作中,一个全面的理论射流与湍流的相互作用,随机结构稳定性理论,适用于理解的带状射流的形成和维护的问题,是至关重要的,以提高等离子体约束在聚变装置。

英文摘要:

A remarkable phenomenon in turbulent flows is the spontaneous emergence of coherent large spatial scale zonal jets. Geophysical examples of this phenomenon include the Jovian banded winds and the Earth's polar front jet. In this work a comprehensive theory for the interaction of jets with turbulence, Stochastic Structural Stability Theory, is applied to the problem of understanding the formation and maintenance of the zonal jets that are crucial for enhancing plasma confinement in fusion devices.
