Non local resonances in weak turbulence of gravity-capillary waves etc15 Tracking Number 85Presentation: Session: Geophysical and astrophysical turbulence 1 Room: Room C Session start: 10:30 Thu 27 Aug 2015 Quentin Aubourg Quentin.Aubourg@legi.grenoble-inp.fr Affifliation: Université Grenoble Alpes, LEGI, CNRS F-38000 Grenoble, France Nicola Mordant nicolas.mordant@ujf-grenoble.fr Affifliation: Université Grenoble Alpes, LEGI, CNRS F-38000 Grenoble, France Topics: - Geophysical and astrophysical turbulence Abstract: We report a laboratory investigation of weak turbulence of water surface waves in the gravity-capillary crossover. By using time-space resolved profilometry and a bicoherence analysis, we study the 3-wave resonant interactions that are responsible for energy transfer among waves. We show that the energy transfer occurs through non local coupling between capillary and gravity waves. |
