Fluid-structure interactions
We study the physical mechanismes which couple simultaneous motions of fluids and structures. Application domains are wide, from transportation systems to nuclear engineering, from aeronautics to wind engineering, and from biomechanics to micro-electronics.
- Biolocomotion: Swimming and Flying in fluidsSébastien Michelin
To move in fluids, insects, fish and other organisms use body-shape deformation sequences to produce the forces that lead to thrust, lift and locomotion. More
- Energy HarvestingSébastien Michelin
Coupling mechanisms between the dynamics of flexible structures and surrounding air/water flows can lead to the self-sustained motion of a solid body, which can be used to generate electricity. More
- Vortex-Induced VibrationsPascal Hémon - Xavier Amandolese - Emmanuel de Langre
Excitation by alternate vortex shedding behind cylinders is probably one the most studied phenomenon in the field of Flow Induced Vibrations of structures. More
- Wind Effects - AeroelasticityPascal Hémon - Xavier Amandolese
Aeroelasticity concerns vibrations induced by airflow on flexible structures, such as airfoil or wind effects on bridges. For instance, the Tacoma bridge collapse is explained by a flutter mechanism that is an aeroelastic phenomenon. More
