DYNAMONDE

The DYNAMONDE project is focused on the study of the complex dynamics of water waves. Experiments play a central role in this project and they are complemented by theoretical and numerical studies. The project is organized with 3 principal tasks: 1) wave turbulence 2) extreme waves ( experimental characterization of rogue waves) 3) wave control (metamaterials for water waves and robustness vs non-linear effects) The experimental technique that we use (Fourier Transform Profilometry developed in the former ANR project Tourbillonde) enables us to get a space-time resolved characterization of water waves (the wave amplitude h(x,y,t) is measured both in space and time). It is particularly well adapted to the study of non-stationary complex phenomena as those involved in the 3 tasks. The analysis of the experimental results will permit to characterize mechanisms that remain to be be understood in the domain of wave turbulence (non-stationarity, effects of heterogeneities), of extreme waves (mechanism of formation of rogue waves, effects of variable bathymetry) or of wave control (metamaterials for water waves, effects of non-linearities). This project is a collaboration between specialist of hydrodynamics, turbulence and waves, with the benefit of complementary point of views.
