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 gradient tensor, quantities useful for probing the results of a simulation, particularly when looking for coherent vortices and coherent structures. Chapters 4 and 5 feature an in-depth discussion of spectral subgrid-scale modeling. Although physical-space models are generally more readily applied, spectral models give insight into the requirements and limitations in subgrid-scale modeling and backscattering. A third special feature is the detailed discussion in Chapter 7, of large-eddy simulation of compressible flows previously only available in articles scattered throughout the literature. This will be of interest to those dealing with supersonic flows, combustion, astrophysics, and other related topics.
Marcel Lesieur, Olivier Metais, and Pierre Comte, form the nucleus of the Grenoble Equipe Modelisation et Simulation de la Turbulence (the Grenoble team for modeling and simulating turbulence) and made significant contributions to the development of subgrid modeling of turbulent flows required for large-eddy simulation, and in the implementation of large eddy simulation methodology for research and applications. These authors were responsible for early research on spectral subgrid-scale closure, and the use of the closure approach in developing the physical space structure function model. More recently the authors have made significant contributions to the development of modeling for compressible turbulent flows.
