概要
- 論文の詳細を見る
The enstrophy cascade in a scalar model of 2D-turbulence is found to be less intermittent than the energy cascade in the 3D case. In particular, the fluctuations of the enstrophy spectral flux decrease with wavenumber in the inertial subrange. Also, the local Lyapunov exponent behaves less intermittently compared to the 3D case.
