Turbulence modification by periodically modulated scale-dependent forcing

The response of turbulent flow to time-modulated forcing is studied by direct numerical simulation of the Navier–Stokes equations. The forcing is modulated via periodic energy-input variations at a frequency ω. Harmonically modulated forcing of the large scales is shown to yield a response maximum a...
