Introduction to two-dimensional turbulence
Abstract
The existence, conditions of occurrence, and success of available numerical models for two-dimensional turbulence are examined. The concept of two-dimensional turbulence is noted to involve rotational structures and molecular diffusion. Several examples of flows with two-dimensional turbulence are cited, including MHD flows within a strong magnetic field, mixing layer flows, and laminar flows. Two-dimensional turbulence in steady flows is investigated, as are the effects of negative turbulent viscosity, freely evolving two-dimensional turbulence, and quasi-geostrophic turbulence and the Jovian atmosphere. Attention is also given to spectral theories of forced two-dimensional turbulence and the use of the concept of enstrophy pseudo-catastrophe at a finite time.
