Emergence of long-range correlations and thermal spectra in forced turbulence

Recent numerical studies have shown that forced, statistically isotropic turbulence develops a ‘thermal equilibrium’ spectrum, E(k) ∝ k 2 , at large scales. This behaviour presents a puzzle, as it appears to imply the growth of a non-zero Saffman integral, which would require the longitudinal veloci...
