Abstract

This paper presents the recent implementation and assessment of the Synthetic-Eddy Method (SEM) and its divergence-free variant, DF-SEM, in the compressible DLR-TAU solver. Unlike most other solvers with synthetic-turbulence capabilities, TAU uses an unstructured grid metric with different cell types, which imposes additional difficulties for the implementation. Nevertheless, it allows for a rather flexible placement of multiple interface planes inside unstructured grids. The methods are assessed in different flow cases from the EU-project Go4Hybrid. To ensure sufficient numerical accuracy, a low-dissipation low-dispersion (LD2) scheme is applied in all simulations.
