Title: Towards scale resolving simulations of aeronautical relevant turbulent flows by means of large scale computing.
Abstract: The current status of LES and its readiness for aerospace applications were recently discussed in the
NASA CFD Vision 2030 report. The report recognised LES with the aid of wall models as one of the
pacing items “for developing a visionary CFD capability required by the notional year 2030.”
However, at the same time, the report stated that “LES requires additional development of the wallmodelling capability that is currently at a very low technology-readiness level.” This criticism is
legitimate, as the use of WMLES has been confined largely in academic research involving relatively
low Reynolds number flows over essentially two-dimensional geometries, often having at least one
direction of statistical homogeneity. This is hardly the case in real-world. In the last years, a significant
effort has been done in BSC to increase the TRL level of LES by deploying high-order low-dissipation
strategies for the simulation of scale resolving turbulent flows into large scale applications. The talk,
will discuss the general strategy followed covering numerical methods, physical based SGS closures
and wall modelling. The current state in incompressible and compressible flows will be analysed
using canonical and industry oriented cases like the high-lift NASA CRM model.
