Lecturer: Olivier Doaré
Basics of tensor algebra. Good knowledge in fluid- and solid-mechanics.
- 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
