Turbulence Modelling

Purpose and focus of SIG

Computational Fluid Dynamics (CFD) has developed to a key technology which plays an important role in design, development and optimization in engineering practice. The role of the ERCOFTAC SIG15 (Special Interest Group for Turbulence Modelling) is closely connected to intensive verification and systematic validation of CFD (Computational Fluid Dynamics) technology for solving the problems of both fundamental importance and industrial relevance. This task has been accomplishing for years in the form of series of workshops on refined turbulence modeling. Focus is on the credibility and reliability of both the numerical methods and mathematical models simulating turbulence. In such a way a large database of simulation results along with detailed comparison with the reliable reference data (experimental, DNS and highly-resolved LES databases) has been assembled. The SIG15 workshops promote the discussion and conclusions about predictive performance of variety of statistical turbulence models (in the Reynolds-averaged Navier-Stokes - RANS - framework), SGS models in the LES (Large-eddy Simulation)-framework as well as hybrid LES/RANS models in a broad range of well-documented flow configurations under the scientists, researchers, users and developers from industry and from the academic field.
