Disentangling inertial waves from eddy turbulence in a forced rotating turbulence experiment

We present a spatio-temporal analysis of a statistically stationary rotating turbulence experiment, aiming to extract a signature of inertial waves and to determine at what scales and frequencies they can be detected. This analysis is performed from two-point correlations of temporal Fourier transform of the velocity fields obtained from time...

Direct numerical simulation of the interaction between unsheared turbulence and a free-slip surface

In this paper, direct numerical simulation is used to study the interaction between turbulence and a free surface. The configuration is original due to the fact that a random force generates turbulence in the vicinity of a plane parallel to the free surface. Turbulence is therefore statistically steady and nearly isotropic at some distance of...
