High-order accurate time integration methods for electromagnetic-thermal analysis
Tobias Gleim (University of Colorado Boulder)
Kurzfassung:
The inductive heating of a metal shaft is influenced by an alternating current inducing a high frequency electromagnetic field, which causes a temperature increase due to the resulting eddy currents. To examine this process, the fully coupled electromagnetic Maxwell equations are combined with heat conduction. Due to the high frequencies of the applied current and the strongly temperature dependent material parameters, high-order accurate numerical methods in space and time are investigated.

Zonal Turbulence Modeling and Reduced-Order Methods for Space Launcher Wake Flows Analyses
Vladimir Statnikov (RWTH Aachen University), Matthias Meinke (RWTH Aachen University), Wolfgang Schröder (RWTH Aachen University)
Kurzfassung:
Turbulent wake flows of generic Ariane 5-like space launcher configurations are investigated using zonal turbulence modeling and reduced-order methods. For two selected, dynamically crucial trajectory stages, i.e., $M_\infty = 0.8$ and $M_\infty = 6$, previously unknown coherent three-dimensional modes are extracted and attributed to the single characteristic frequencies and wave lengths which are responsible for critical side loads on the nozzle structure.
