West-east High Speed Flow Field Conference

Abstract

The behavior of a variational multiscale LES model is studied for flows past bluff 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 flexible mooring is then computed. The interest of variational multi-scale as compared to usual Large Eddy Models is put in evidence.
