Zonal Flow Patterns: How Toroidal Coupling Induces Phase Jumps and Shear Layers

Z. B. Guo, P. H. Diamond

摘要:

本文提出了一种新的带状流斑图形成的调频机理。该模型预测的概率分布函数的流强度以及演变的特征空间尺度。磁环诱导的全球相动力学,以确定的空间结构的流动。一个关键的结果是观察到的全球相位图案可以导致带状流的形成在湍流不均匀性的情况下。

英文摘要:

A new, frequency modulation mechanism for zonal flow pattern formation is presented. The model predicts the probability distribution function of the flow strength as well as the evolution of the characteristic spatial scale. Magnetic toroidicity-induced global phase dynamics is shown to determine the spatial structure of the flow. A key result is the observation that global phase patterning can lead to zonal flow formation in the absence of turbulence inhomogeneity.
