Abstract
The study of turbulence models is commonly performed by Computational Fluid Dynamics. This work applies the SAS (Scaled-Adaptive Simulation) model to describe the flow around a cylinder with a Reynolds number (Re) of $3900$ in different mesh sizes. This work also verifies that the theoretical value of the Smagorinsky constant, even with turbulence limiter in the production, can generate good results. The drag, lift and Strouhal coefficients are compared with experimental data. The model is able to obtain good results, with fewer computational requirements than the LES models and with a good representation of the flow vorticity, which makes it more practical for fluid structure analysis or other computer intensive flow simulations.
