Abstract

A hybrid Overset LES approach has been presented to efficiently account for sound source mechanism in aeroacoustics. This contribution pre-sents the latest results of the calibration process of Large eddy simulation in homogenous decaying isotropic turbulence. At first the simulation parameter, setup and procedure of initialization is illustrated briefly and subsequently, the results are discussed in detail. As we can get from the overall good agree-ment with DNS reference data, the subgrid-scale modelling is properly ensur-ing for the correct amount of dissipation in the high wavenumber regime. Fur-ther information about near wall performance in more realistic flow has to be investigated in turbulent channel flow.
