Laboratory for Flow Instabilities and Dynamics

Jakob von Saldern

Jakob G. R. von Saldern completed a degree in Physical Engineering at the Technical University of Berlin, specializing in Thermodynamics and Control Engineering. In 2018, he worked as a student assistant at the Chair of Combustion Dynamics and served as a tutor for the course "Fundamentals of Measurement and Control Engineering" in the winter semester of 2018/2019. During an exchange semester at NTNU Trondheim, he wrote his master's thesis on the topic of thermoacoustics in can-annular combustors. Since graduating in 2019, he has been working as a doctoral candidate at the Laboratory for Flow Instabilities and Dynamics, focusing intensively on research in the field of fluid mechanics. A major focus of his work is on the thermoacoustic design of a 100% capable hydrogen burner in collaboration with MAN Energy Solutions. The goal of this project is to develop an efficient hydrogen burner that enables the use of hydrogen as a fuel. Furthermore, he is engaged in the data assimilation of flow fields using Physics-informed Neural Networks (PINNs). His main focus lies in the development of "Mean Field Consistent Closure" models for the transport equations of coherent structures. This approach combines methods from physics with artificial intelligence, enabling more precise modeling and prediction of coherent structures in turbulent flows, including reacting flows. Through his dedication to the development of climate-neutral technologies through work on hydrogen burners and his research aimed at improving the understanding of coherent structures in turbulent flows using PINNs, Jakob G. R. von Saldern makes a valuable contribution to addressing current challenges in the field of energy engineering and fluid mechanics.
