Adjoint and self-adjoint filter operators are introduced, such that large-eddy simulation (LES) with a spatially variable filter width satisfies important physical properties: Conservation of momentum and dissipation of kinetic energy. The combination of an arbitrary nonuniform explicit filter with the Smagorinsky model leads to a new model of the turbulent stress tensor, which includes Cited by: SUBMIT BOOK PROPOSAL. Online Store.

Large-Eddy Simulations of Turbulence is an ideal introduction for people new to LES [large-eddy simulation], direct numerical simulation and Reynolds-averaged Navier-Stokes simulation, and as a reference for researchers. Of particular interest in the text are the detailed discussion, in Chapter 2, of vorticity, pressure, and the velocity. Key words: Large-Eddy Simulation, Subgrid-Scale Models, Katabatic Flow, A Posteriori Testing 1 Introduction Over the past few decades, large-eddy simulation (LES) has become an invaluable tool for investigating the structure and characteristics of atmospheric boundary layer ﬂows [1].

Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES) have become powerful tools for the investigation of particle-laden turbulent flows with the help of advances in computing resources. The hybrid Eulerian-Lagrangian approach plays a key role in Cited by: 1. Large Eddy Simulation study of a fully developed thermal wind-turbine array boundary layer.
