Large Eddy Simulation for Incompressible Flows, An Introduction, 3rd Edition

摘要

This new edition of Pierre Sagaut's large eddy simulation (LES) book is timely and extremely welcome in the fluid dynamics community. Compared to the second edition, which appeared two years earlier, the original material has been expanded by 130 additional pages and the relevant literature survey now lists more than 800 references. Significantly new material in a number of important areas has been added to increase coverage of this fast-growing and challenging field of turbulent flow simulations. Turbulent flows are of considerable importance in many applications in aerospace engineering, geophysics, and astrophysics. High-Reynolds number turbulent flows involve a broad range of length and time scales. The largest scales are related to the specific geometry, boundary conditions, and regimes considered, and the smallest are associated with the dissipation of turbulent energy through viscosity. A predictive closed theory of turbulent flows has not yet been established and is unlikely to emerge in the foreseeable future. Moreover, it is not possible to compute most high-Reynolds (Re) number turbulent flows by direct numerical simulation (DNS) resolving all relevant scales in space and time. Instead, at least part of the unsteady turbulent motion must be approximated to make these calculations feasible.
