The residual-based variational multiscale formulation for the large eddy simulation of compressible flows
نویسنده
چکیده
The residual-based variational multiscale formulation is applied to develop a large eddy simulation (LES) model for compressible flows. In addition, a mixed model, in which a deviatoric Smagorinsky subgrid stress term is added to the RBVM terms to better model the Reynolds stresses is proposed. These models, along with the dynamic Smagorinsky-Yoshizawa-eddy diffusivity model are tested in predicting the decay of homogenous turbulence. For most relevant measures, it is observed that the RBVM models are more accurate than the dynamic Smagorinsky-type model.

A Variational Multiscale Method for the Large Eddy Simulation of Compressible Turbulent Flows on Moving/Deforming Unstructured Grids
In this extended abstract a three level formulation of the variational multiscale (VMS) large eddy simulation (LES) method for turbulent flow computations on moving/deforming grids is presented. A consistent method to improve the VMS-LES method by computing the small-scale Smagorinsky constant (C′ s) dynamically as the flow develops (dynamic VMS-LES) is also developed. An application of VMS-LES...
متن کاملVariational Multiscale Residual-driven Turbulence Modeling for Large Eddy Simulation of Incompressible Flow
The objectives of recent variational multiscale work in turbulence have been to capture all scales consistently and to avoid use of eddy viscosities altogether. This holds the promise of more accurate and efficient LES procedures. In this work, we describe a new variational multiscale formulation, which makes considerable progress toward these goals.

A variational multiscale method with multifractal subgrid-scale modeling is proposed for large-eddy simulation of turbulent flow. In the multifractal subgrid-scale modeling approach, the subgrid-scale velocity is evaluated from a multifractal description of the subgrid-scale vorticity, which is based on the multifractal scale similarity of gradient fields in turbulent flow. The multifractal sub...
متن کاملThe multiscale formulation of large eddy simulation: Decay of homogeneous isotropic turbulence
The variational multiscale method is applied to the large eddy simulation ~LES! of homogeneous, isotropic flows and compared with the classical Smagorinsky model, the dynamic Smagorinsky model, and direct numerical simulation ~DNS! data. Overall, the multiscale method is in better agreement with the DNS data than both the Smagorinsky model and the dynamic Smagorinsky model. The results are some...
متن کاملVariational Multiscale LES and Hybrid RANS/LES Parallel Simulation of Complex Unsteady Flows
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 element/volume formulation on unstructured grids. First, the behavior of a VMS-LES model with different subgrid scale models is investigated for the flow past a circular cylinder at Reynolds number Re =3900. Second, a new...
