Turbulente Strömungen

Turbulence is different from the courses you have taken so far. Here, equations will be important, but much of the theory is based on scaling arguments. The comprehension of dimensional analysis and scales will be important. The objective of the course is to provide the theory and knowledge for understanding, for example, of publications and seminar talks on the subject, and to serve as a basis for making a contribution to the field.
