This thesis aims at detecting large-scale turbulent structures in incompressible Rayleigh-Taylor mixing layers at low Atwood number. Various statistical quantities...

Résumé Traduit : This thesis is a contribution to the study of turbulence in the near field of a jet exit, with or without swirl. We use an experimental setup which...

Since the pioneer work of Townsend (1956), it is now well known that a coherent motion persists in most of shear flows. Following the lines of Townsend's issues,...

The two-dimensional hydrodynamics is of major interest for understanding of atmospheric phenomena as various as formation structures such as hurricanes. Thermal...

Tidal bores are surge waves propagating upstream rivers as the tide rushes into estuaries. They induce large turbulences and mixing of the river and estuary flow of...

The urban surface layer in neutral conditions is studied based on an atmospheric wind tunnel simulation and velocity measurements by hot wire anemometry and...

Electromagnetic flow control in seawater allows to modify the flow by means of a Lorentz-Laplace field of force. This body force is produced by electromagnetic...

We experimentally investigated the temporal dynamics and the different transitions associated to the generation of large scale coherent structures in two-dimensional...
