PA - C8 - MEC661H : Fluid-structure Couplings in Offshore Wind and Marine Renewable Energies

Domaine > Mécanique.


Lecturer: Olivier Doaré


Eligibility/Pre- requisites 

Basics of tensor algebra. Good knowledge in fluid- and solid-mechanics. 

Learning outcomes 

This course


  • gives the necessary knowledge to understand the physical phenomena that occur when an offshore structure interacts with currents, waves and wind,
  • provides an exhaustive overview of the actual issues and techniques in the marine renewable energies industry,
  • presents some numerical tools to solve basic design problems in fluid-structure interaction.

Course main content 

This course is divided into three parts.

In the first part (3 lectures) a review of the basics of fluid-structure interactions is presented. The main physical phenomena that arise in all offshore industries will be theoretically addressed:
- The added mass, damping and rigidities that affect the dynamics of structures in still or flowing fluids.

- The flow-induced vibrations, such as vortex-induced vibrations, coupled mode flutter, drag and lift crisis instabilities.
- The interactions between floating structures and waves.

In the second part (4 lectures), the different technologies will be presented by industrials: - Wind offshore technologies
- Marine thermal energy technologies
- Wave energy technologies

- Water currents energy technologies
The last two sessions will be devoted to a numerical project
