REST HF-9 test case: Large-Eddy Simulation of DLR's BKD configuration

Résumé

The results from the large-eddy simulations of BKD bench from DLR (Gröning et al., JPP, 2016) are shown in this contribution. The code is applied to two operating points of the hydrogen ramping experiment from Gröning et al. (CEAS space journal, 2016). The solver retrieves the dominant unstable modes that are observed experimentally. However, the grid resolution is found to have a major impact on the prediction of the dominant mode. While average quantities are weakly impacted by a coarsening of the mesh, the final prediction of the mode growth and its limit cycle can be completely modified.
