On the energy spectrum of forced two-dimensional turbulence

Abstract

We study the energy spectrum of forced two-dimensional turbulence in a doubly periodic domain damped by a general (linear) dissipation and driven by a forcing, for which the characteristic wavenumber either approaches, or fluctuates in time about, a constant. It is shown that the energy spectrum E(k) satisfies ∑ k(k 2 − s)D(k)E(k) = 0, where s is the… (More)
