Abstract

This paper presents the recent implementation and assessment of the Synthetic-Eddy Method and its divergence-free version in the unstructured compressible DLR-TAU solver. Synthetic turbulence can either be injected at the inflow or at interface planes inside the flow domain, which are defined via simple user input. The methods are successfully applied to quasi-2D flow cases of varying complexity, ranging from a flat-plate boundary layer up to a 3-element airfoil near stall. The simulations yield satisfying agreement with mean-flow reference data, but still leave room for improvements of the adaptation length to fully-developed turbulence.
