Ph.D. Course on

Vorticity, Vortical Flows and Vortex-Induced Vibrations

Technical University of Denmark, August 26-30, 2019

Course description

Vorticity is a measure of the spinning motion of a fluid. Understanding the sources, dynamics and structure of vorticity, in particular the interaction of vortices, is of key importance in fluid mechanics. The course will cover a range of topics:

  • Generation of vorticity at interfaces and free surfaces
  • Vortex filaments and their instabilities
  • Instability of swirling flows
  • Vortex breakdown
  • Wakes of bluff bodies
  • Topology of vortical flows
  • Vehicle aerodynamics
  • Fluid-structure interaction
  • Aerodynamics of wind turbines

Thomas Leweke, CNRS / Aix-Marseille Université, France
Jens Nørkær Sørensen, Technical University of Denmark
Morten Brøns, Technical University of Denmark


The course is designed for PhD-students and final-year graduate students being familiar with some knowledge of fluid mechanics.

Working Load

The course gives 5 ECTS corresponding to approximately 130 hours in total, which includes work during the course period at DTU (lectures, exercises, and discussions) as well as project work after the course week.

Study Material

Course material will be provided to the participants.


All lectures will be given in English.


5 ECTS credits can be awarded for participation. This requires active participation during the course period as well as subsequently completing a project report to be handed in by October 1, 2019. The work load for the project is estimated to 40 hours. The course will be graded passed/not passed.
