Energy dissipation and flux laws for unsteady turbulence

Direct Numerical Simulations of spatially periodic unsteady turbulence show that the high Reynolds number scalings of the instantaneous energy dissipation rate and interscale energy flux at intermediate wavenumbers are qualitatively different from the well-known $u'(t)^{3}/L(t)$ cornerstone scalings of equilibrium turbulence where $u'(t)$ and $L...
