Computation of complex unsteady flows around bluff-bodies through VMS-LES modeling

Abstract : The behavior of a variational multiscale LES model is studied for ows past blu bodies. The circular cylinder is studied for a Reynolds 3900. Subgrid scale eddy viscosities of Smagorinsky, Vreman and the WALE model are compared. The vortex induced motion of a spar equipped with strakes and exible mooring is then computed. The interest of variational multi-scale as compared to usual Large Eddy Models is put in evidence.
