Structural instability of two-dimensional turbulence

Research output: Contribution to journalArticlepeer-review


Weakly anisotropic steady are found for both inverse and direct cascades in two-dimensional turbulence of an incompressible fluid. The degree of anisotropy is shown to increase for both spectra: as (kL) -2 3 upscales and as (kΔ)2 downscales from the pump. A weakly anisotropic intermediate-scale pumping may thus produce a substantially anistropic turbulence in the inertial intervals of scales.
