Parallel Simulation of Complex Unsteady Flows with Variational Multiscale LES and Hybrid RANS/LES
Abstract : We study a new hybrid RANS/Variational Multiscale LES (VMS-LES) model for bluff body flows. The simulations have been carried out using a parallelized solver, based on a mixed \textcolor{Black}{finite} element/\textcolor{Black}{finite} volume formulation on unstructured grids. Parallel performances are analysed. The behavior of a VMS-LES model with different subgrid scale models is investigated for the flow past a circular cylinder at Reynolds number {\it Re} =3900. Second, a new strategy for blending RANS and LES methods in a hybrid model is described and applied to the simulation of the flow around a circular cylinder at {\it Re} = 140000.
