Different regimes for water wave turbulence

We present an experimental study on gravity capillary wave turbulence in water. By using space-time resolved Fourier transform profilometry, the behavior of the wave energy density |ηk,ω|2 in the 3D (k,ω) space is inspected for various forcing frequency bandwidths and forcing amplitudes. Depending o...
