Abstract

We perform Direct Numerical Simulations (DNS) of electromagnetically fractal-forced and Rayleigh-damped two-dimensional flows. Our simulations show broad band power law energy spectra. When the fractal dimension of the magnets’ distribution is D f =0.5 then p ≈ 2.5 in agreement with previous laboratory experiment. Moreover, when the fractal distribution of magnets is changed, p varies linearly with D f , the fractal dimension of the magnet set up. Hence, fractal control of the energy spectrum is possible.
