An intense, homogeneous and isotropic turbulence is generated by an 8x8 array of jets pointing upwards at the bottom of the basin. We study free-surface deformations induced by hydrodynamic turbulence. In a second stage, we will study the mutual interaction between hydrodynamic turbulence and waves generated by an electromechanical shaker at the free surface: attenuation or amplification of free-surface waves by hydrodynamic turbulence and energy exchange in particular between hydrodynamic turbulence and wave turbulence. |
