Within the EU program Horizon 2020 the German Aerospace Center (DLR) and the partners evolve in the project HiFi-TURB (High-Fidelity DNS/LES for Innovative Turbulence Models) a new generation of reliable anisotropy-resolving turbulence models, able to predict accurately separated and vortical flows for the European aeronautics industry to be used in RANS and Hybrid RANS-LES methods – forming the CFD backbone in industry.With the innovative and ambitious objectives and goals of the HiFi-TURB project, using for the first time large and highly-refined LES/DNS data bases in a systematic manner, including the innovative use of AI and big-data technologies for feature detections towards new/improved turbulence models, the present gaps of capabilities in modelling challenging conditions within the flight envelop will be largely removed. According to the latter and driven by the work program and the technical objectives described above, industry will be supported and – to a certain extent – educated on how to run their simulations more ‘automatically’ with a minimum of user interventions – related to modelling aspects. Based on the present and even more future situation concerning HPC networks, it is the ambition of the HiFi-TURB project to forming the backbone in reaching the goals of resolving all relevant flow features in short times.
The DLR-Institute of Aerodynamics and Flow Technology leads a Work Package in HiFi-TURB and is mainly engaged in deriving and investigating new turbulence model terms based on its expertise in turbulence modeling.
