Abstract
Direct numerical simulations of the full two phase Navier-Stokes equations including surface tension in order to investigate capillary wave turbulence are performed for the first time, using the code Gerris [1]. Wave turbulence concerns the study of the statistical properties of a set of numerous nonlinear interacting waves [2]. Waves are observed to follow the linear dispersion relation of capillary waves and a stationary regime is reached. The wave height power spectrum in the wave-number-space or in the frequency-space exhibits power law regimes and shows good agreement with weak turbulence theory [2]. Finally, the scaling of the spectrum with the injected power will be discussed and compared with theoretical and experimental works.
