Fundamentals of Fluid-Solid Interactions

École Polytechnique via Coursera


What is fluid-solid interactions ? It is what happens when the motions of a fluid and of a solid are somehow coupled. This happens all the time, around you when leaves flutter in the wind, inside you when your heart beats, above you when wings of a plane vibrate, under the sea... The idea behind this MOOC is to give you the basic tools to be able to predict and eventually mitigate things called flutter, galloping, sloshing, vortex-induced vibrations, added mass, to cite a few.

We are going to consider any possible domains of applications such as civil engineering, aerospace engineering, nuclear engineering , ocean engineering, biomechanics and even food processing !

This is why we called the course “Fundamentals of Fluid Solid Interactions ”. There are so many phenomena and so many models that we need to work together on the basic mechanisms .

If you want to see how fluid-solid interactions work, and be able to use that knowledge, join us !

A first session of the course was run in early 2016, with learners from over 100 countries. It is now available with subtitles, in English and now in Chinese.
