Turbulence under Fractal Fourier Decimation

We present a systematic investigation of 3D turbulent flows evolved on a highly decimated set of Fourier modes. In particular, we investigate the change in small-scales intermittency when the flow is constrained to excite only a fractal set of modes but keeping the symmetries of the original 3D Navier-Stokes equations.
