The dissipation rates of the basic second-order moments are the key parameters controlling turbulence energetics and spectra, turbulent fluxes of momentum and heat, and playing a vital role in turbulence modelling. Here, we publish the results of Direct Numerical Simulations of stably stratified turbulent plane Couette flow, which are used to evaluate dissipation rates of the basic second-order moments and revise the energy and flux-budget turbulence closure theory for stably stratified turbulence.
