Abschlussarbeiten

The Institute of Fluid Mechanics supervises student research projects, bachelor and master theses in German or English language in all scientific fields.

The academic teachers of our institute are responsible for and monitor these theses. In addition, the head of the respective division or the doctoral candidates working on relevant projects supervise every thesis intensely. During their thesis period, the students are integrated in the institute’s team and the projects of the respective division, i. e. they fully apprehend the implication of their work in current research projects of the institute.

If you are interested in doing your thesis at the LSTM, please refer to the following information on our research groups.
