Shock-induced separation and flow control – and their relevance for air- and space-transportation systems


For the third time, the Daimler and Benz Foundation, together with the Alumni Association, invited scholarship holders and alumni to a virtual meeting, where a scholarship holder reported on her work and almost 30 listeners joined in.

With applications in the sectors of communication, navigation, and transportation, as well as climate-research efforts, air- and space-transportation systems directly influence our daily life. Payloads, fuel consumption, and sometimes even the functionality of such systems are strongly influenced by aerodynamic features. The aerodynamic behavior is affected by phenomena related to shock-induced separation in particular: shock-induced separation can induce strong local pressure and heat loads and thus endanger the integrity of the system. Therefore, being able to mitigate or even prevent flow separation by targeted control of the flow is of great interest. To be able to develop effective flow-control methods, an in-depth understanding of the flow physics – both with and without flow control – is required. The talk presents fundamental research on these topics and also discusses (primarily experimental) methods to get access to important phenomena in these flows.

Anne-Marie Schreyer received her PhD from the University of Stuttgart and conducted research at Princeton University and Aix-Marseille Université. Since 2017, she has been leading her Emmy Noether Junior Research Group at the Aerodynamics Institute of RWTH Aachen University.
