SC Seminar: Junis Abdel Hay
Junis Abdel Hay, SciComp Title: Modelling Real Acoustic Absorbers for Computational Aeroacoustics Abstract: Acoustic liners are widely used as acoustic absorbers in the inlet and bypass duct of aero-engines. Commonly used acoustic liners are Helmholtz resonator arrays and consist of … Continue reading
SC Seminar: Marc Schwalbach
Marc Schwalbach, von Karman Institute (VKI) Title: Cold-to-hot transformation for adjoint optimization of turbomachinery components Abstract: Due to the centrifugal forces experienced by turbomachinery components in operation, structural deformations occur such that the running âhotâ structure differs from the resting … Continue reading
SC Seminar: Simon Gottschalk
Simon Gottschalk, Fraunhofer ITWM Title: The One-shot method for optimization problems with underlying PDEs Abstract: Optimization problems with underlying PDEs appear in disciplines like geophysics, medical imaging, atmospheric science and aerodynamic shape design. Conventional approaches -known from the nonlinear optimization … Continue reading
SC Seminar: Domenico Quagliarella
Prof. Domenico Quagliarella, Italian Aerospace Research Center (CIRA) Title: Risk measures and optimization under uncertainty Abstract: Many industrial optimization processes must take account of the stochastic nature of the system and processes to be designed or re-designed and have to … Continue reading
SC Seminar: Andrea Walther
Prof. Andrea Walther, Institut fĂŒr Mathematik, UniversitĂ€t Paderborn Title: On the optimization of piecewise smooth functions Abstract: This talk presents the abs-normal form for piecewise linear functions, which can be used for the optimization of piecewise linear function. Such an … Continue reading
SC Seminar: Jonas Kusch
Jonas Kusch, RWTH Aachen/TU Kaiserslautern Title: Frequency Based Preconditioning And Smoothing for Shape Optimization Abstract: In this talk, a preconditioner for shape optimization in the case of small Reynolds numbers will be derived. The preconditioner mimics the local Hessian behavior, … Continue reading
