Fluid Structure Interaction

Fluid-structure interaction (FSI) phenomena can occur whenever a fluid comes into contact with a solid. The interactions likely to occur in this case are crucial in fields such as aeronautics, civil engineering, bio-mechanics, the nuclear industry, renewable energies and so on. Understanding these phenomena through modeling and simulation is therefore essential for fluid mechanics engineers.

This course aims to introduce the basic concepts associated with modeling and numerical simulation of fluid-structure interactions.
