Content, Learning Outcome and Preconditions

Content

This module gives an introduction into turbulence research. It encompasses experimental observations as well was as intuitive model-based and theoretical approaches to describe turbulent processes. Starting point is the physics of low-dimensional chaotic systems. After a brief introduction into the basics of neutral fluids and magnetized plasmas the most important linear instabilities will be discussed before the influence of different types of nonlinearities on the dynamics of the fluid is demonstrated. Next fully developed turbulence will be treated for three- and two-dimensional fluids with an emphasis on magnetized plasmas. The different concepts will be illustrated with examples from astrophysics, fusion research and engineering sciences.  The lectures will be accompanied by computer exercises using numerical techniques to analyze time traces from turbulence experiments. This includes Fourier and wavelet techniques as well as non-linear methods such as bicoherence analyses.

Learning Outcome

After successful completion of this module the student is able to

  1. explain the basic properties of turbulence
  2. name the characteristic differences between chaos and turbulence
  3. explain the important mechanisms leading to linear instabilities
  4. describe experimental techniques to investigate turbulence
  5. apply the basic numerical techniques to analyze turbulent time traces

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.

Exam Repetition

There is a possibility to take the exam at the end of the semester.

Condensed Matter

When atoms interact things can get interesting. Fundamental research on the underlying properties of materials and nanostructures and exploration of the potential they provide for applications.

Nuclei, Particles, Astrophysics

A journey of discovery to understanding our world at the subatomic scale, from the nuclei inside atoms down to the most elementary building blocks of matter. Are you ready for the adventure?

Biophysics

Biological systems, from proteins to living cells and organisms, obey physical principles. Our research groups in biophysics shape one of Germany's largest scientific clusters in this area.
