Hydrodynamics (turbulent kinetic energy) production divided by the dissipation rate from DNS for the homogeneous Rayleigh-Taylor instability.

Hydrodynamics (turbulent kinetic energy) production divided by the dissipation rate evolutions from direct numerical simulation (DNS) of homogeneous Rayleigh-Taylor (HRT) instability. In HRT, production is P = kdot + eps, where kdot = dk/dt + eps, with k the turbulent kinetic energy and eps the dissipation rate of turbulent kinetic energy. These tables contain P/eps, a measure of the non-equilibrium nature of the turbulent flow.
