Course Content
The course content is focused on non-equilibrium turbulence, advanced analysis methods and related experimental studies at the DTU Turbulence Research Laboratory. The main topics are:
- Review of the main classical views of turbulence, including
- The Kolmogorov/Richardson/Batchelor (K41) equilibrium theory
- Rapid Distortion Theory
- Classical approaches to understanding turbulence
- Historical and more recent developments of non-equilibrium turbulence research
- Experimental/computational approaches used @ DTU TRL (including design tools for design of PIV/PTV experiments)
- Proper Orthogonal Decomposition (POD) techniques and developments at the DTU TRL
The course includes a tour of the newly established DTU TRL laboratory facilities at DTU Construct.
Student target group
The course is intended primarily for PhD-students that have an interest in (non-equilibrium) turbulence, advanced experiments and/or advanced analysis tools for turbulence research. MSc-students are also welcome to a limited extent. The participants should have general knowledge of fluid mechanics/turbulence and basic Python programming. We will cover the basic principles behind the POD method as well as those of optics necessary to attain a basic understanding of the course content. The course has an upper limit of 30 participants.
Course Credits and Expected Work Load
With assignments, the course corresponds to a total of 3 ECTS credits, or 84 hours (pass/no pass). A course certificate can be provided upon request and finalized course with active participation: Please fill the following form and write 'specialized course with Clara Marika Velte' in the field "Course number and title (1)".
Activities to obtain ECTS credits:
At the beginning of the course, you will give a 5 minutes poster presentation of your PhD-project. The course work will also include one of the following, depending on the main interest of the student:
- POD analysis of measurement data from the DTU TRL lab facilities. A guiding script in Python will be made available.
- Design of a planar or volumetric (laser or LED based) experiment for turbulence measurements.
Based on the chosen task from the list above, you will write a report (in the form of a "paper", 5 pages) as part of the course work. This is to be submitted no later than 2 weeks after the course end (i.e. June 16).
As an option, it is possible to follow the course and lectures without earning course credits.
