Laboratory for Flow Instabilities and Dynamics

Jens Müller

Jens Müller graduated in M.Sc. Aerospace Engineering at the TU Berlin in 2018. As a research associate at the Laboratory for Flow Instabilities and Dynamics, he is responsible for supervising and teaching the course "Data analysis techniques in thermo-fluid dynamics".

As part of his doctoral research, he is working on theoretical as well as data-driven empirical analysis methods. These methods are used for the targeted development and optimization of flow control applications. For example, these methods are applied to gas turbines in natural gas power plants and Francis turbines in hydroelectric power plants for the suppression of global flow instabilities, which pose a risk to the safe operation of such plants.  Furthermore, the methods are used on wind turbine rotor blades to reduce trailing-edge noise, which is a major source of noise pollution from wind turbines.
