Abstract
We investigate the behavior of turbulent systems in geometries with one compactified dimension. A novel phenomenological scenario dominated by the splitting of the turbulent cascade emerges both from the theoretical analysis of passive scalar turbulence and from direct numerical simulations of Navier-Stokes turbulence.
摘要
我们研究了具有一个紧致化维度的几何形状中湍流系统的行为。从被动标量湍流的理论分析和纳维-斯托克斯湍流的直接数值模拟中都出现了一种新的由湍流级联分裂主导的唯象情景。
