  • To overview engineering fluid-structure interaction (FSI) problems in the industry.
  • To learn models and methods of solving FSI problems.
  • To understand the coupled equation system for FSI scenarios.
  • To acquire the knowledge of aero-/hydro elasticity and aero-/vibro acoustics.
  • To grasp general numerical methods and popular commercial software for solving FSI problems.
  • To learn the writing for a project report, and to present the project. 


  • Classical FSI effects: added mass, sloshing, and slamming, etc.
  • Aero-/hydro elasticity (flow-induced vibrations, aero-vibro acoustics)
  • The coupled governing equations for FSI.
  • Simplified models and numerical methods for FSI.
  • General numerical techniques in CFD and FEM (overview). 
  • An extensive project as the last/utmost part of the course: one of the FSI topics (marine techniques, offshore architectures, aerospace, automotive, sailing sports, vehicle safety, biomechanics) can be selected for the project based on the student group’s interest. Moreover, the group is free to propose their own project topic.

Learning outcomes

  • Understand methods and techniques for classical FSI such as aero/hydro elasticity, and aero-vibro acoustics, etc.
  • Be capable of identifying and analyzing dominant mechanisms in various engineering scenarios.
  • Be capable of deriving and explaining the governing equations for the coupled flow and structure motion/deformation.
  • Understand FSI coupled algorithms and numeral methods.
  • Grasp how to use commercial software, which is popular in the industry, to simulate FSI problems.


The course consists of three sections on methods, exercises, and an extensive project. The first two sections are devoted to understanding the basics. In total, 6 lectures are scheduled once per week. After the lectures, a 3-week project targeting industrial applications is arranged with the options: marine techniques, offshore architectures, aerospace, automotive, biomechanics, sailing sports. A student can pick up one of the options that best fits his/her educational background. The project work will be documented in the form of a written report and presented at the end.

How to apply?

Please send your CV and course transcripts (merged in one file) to At the beginning of the CV, please write 1-2 sentences to outline your current programme and which specific topic/problem in FSI you are interested in. 

Deadline for submission of application: 15 December, 2021
