Large Eddy Simulation (LES), hybrid LES-RANS, Detached Eddy Simulation (DES) and unsteady RANS

is given at Chalmers, Gothenburg, Sweden, 29-31 October, 2014. LES is suitable for bluff-body flows or flows at low Reynolds numbers. To extend LES to cover industrial flows at high Reynolds numbers, new approaches (hybrid LES-RANS, DES, URANS, SAS, PITM, PANS) must be used. They are all based on a mix of LES and RANS.

The course will give an introduction to LES and these new methods. LES, or any of the new approaches, is the first step when performing accurate CAA (Computational Aero-Acoustics). Lectures will be given in the mornings; in the afternoons there will be workshops using Matlab on PC Workstations.

In the workshops, the participants will use Matlab for analyzing SGS models, SAS, PANS, DES and DDES. Matlab scripts will be used to generate synthetic (isotropic and anisotropic) turbulent fluctuations for inlet boundary conditions and embedded LES.

The number of participants is limited to 16.
