MEGAFLOW for AIRBUS-D — Applications and Requirements
The MEGAFLOW projects — I and II — are key drivers for CFD (Computational Fluid Dynamics) technology research within Germany, possibly in Europe as a whole. MEGAFLOW combines the development of most modern CFD tools and suites with the daily application of these tools for aircraft design and data processes. Due to aircraft industries being forced to optimize their designs and to give performance predictions in highest accuracy terms, while the time for design cycles are reduced, high level CFD becomes more and more a basic design tool. However, in many cases CFD reaches its limits due to the ongoing increase of complexity with respect to geometry and flow conditions. Further development of physical flow modeling and further validation of new application cases need to be continued. This paper describes AIRBUS-D requirements on methods and tools development in MEGAFLOW, validated by AIRBUS-D test cases. It outlines which requirements are fulfilled, which are still open, and which have had to be added over the years.
