| Thu February 17th 2022 16:00 – 17:00 Online | Seminar | Physical Modeling and Advanced Numerical Methods for the Digital Aircraft Cornelia Grabe |
Details:To significantly contribute to the EU target of climate neutrality in 2050 while concurrently maintaining safety standards and competitiveness, the aviation sector faces a transformation that will affect the design of aircraft. The design and optimization process needs to be substantially accelerated to mitigate high financial risks in order to deliver new, emission-reduced aircraft timely to market. This can be achieved with an extensive and integrated usage of digital tools throughout the design process ultimately leading towards the “Digital Aircraft”. The introduction of high-fidelity numerical methods permits a reliable evaluation of new technologies and designs especially at the early stages of the design process and avoids expensive and time-consuming testing using physical demonstrators.In the C²A²S²E department of the Institute of Aerodynamics and Flow Technology at the German Aerospace Center, we develop disciplinary methods for external aerodynamics including turbulence and transition modeling, scale-resolving simulation methods, numerical algorithms and surrogate models as well as multi-disciplinary analysis (MDA) and optimization (MDO) methods to be applied on industrial grade aircraft configurations. During my talk I will highlight our recent contributions and activities in the field of turbulence and transition modeling including Differential Reynolds-Stress Models and its extensions for accurately predicting turbulent boundary layers subjected to adverse pressure gradients, laminar-turbulent transition prediction methods with varying complexity and the status and challenges of applying and embedding scale-resolving simulation methods for industrially-relevant aeronautical configurations. Additionally, I will briefly outline our activities in the field of wind energy. | ||
