关于二维turbulence中八分之一定律的一点注记

A critical note on one-eighth law in 2D turbulence

Sagar Chakraborty

摘要:

我们批判性地回顾了各种试图证明八分之一定律在二维湍流和调和。本文证明了二维非受迫不可压高雷诺数湍流的1 - 8定律。对于涡度拟能级联占优区,本文还导出了两点二阶速度关联函数对时间导数的精确表达式。

英文摘要:

We critically revisit the various attempts to prove one eighth law in 2D turbulence and reconcile them. Herein, the one-eight law has been proved for unforced 2D incompressible high Reynolds number turbulence. An exact expression of the time derivative of two-point second order velocity correlation function is also derived for the enstrophy cascade dominated regime.
