Dissipation in unsteady turbulence

Recent experiments and simulations have shown that unsteady turbulent flows display a universal behavior at short and intermediate times, different from classical scaling relations. The origin of these observations is explained using a nonequilibrium correction to Kolmogorov’s energy spectrum, and the exact form of the observed universal scaling is derived.
