Isotropic turbulence receives a continuous effort for an increasingly refined description, but complex effects modify the dynamics of turbulence, and are poorly understood. Instances of distorted turbulence by external body forces are present throughout natural and industrial flows, as in geophysical flows submitted to the Earth’s rotation, and to density or temperature stratification. We focus here on the effects of stable stratification and solid body rotation on the dynamics and structure of homogeneous turbulence.We perform high resolution Direct Numerical Simulations (DNS), to characterize the 3D structure of anisotropic turbulence and its statistical properties. Vertical structures appear in rotating turbulence, or a layering in stably stratified turbulence, depending on the rotation rate and the density gradient, parameters that are varied in our simulations (see [8]).
