On the influence of wind on extreme wave events
This work studies the impact of wind on extreme wave events, by means of numerical analysis. A High Order Spectral Method (HOSM) is used to generate freak, or rogue... -

Harmonic forcings in rotating flows: zonal winds, inertial waves and instabil...
A huge amount of energy is stored in the spin and orbital motions of any planet. Harmonic forcings such as libration, precession and tides are capable of conveying a... -
Vortex dynamics - Application to the environmental impact of immersed structures
The study was performed experimentally. The vortices are generated by interaction between a monochromatic wave and a horizontal thin plate used as vortex generator.... -
Experimental analysis of the unsteady flow and instabilities in a high-speed ...
The present work is a result of collaboration between the LMFA (Laboratoire de Mécanique des Fluides et d’Acoustique, Ecole Centrale de Lyon – France), Snecma and the... -
