Book Description
This book provides students and researchers in fluid engineering with an up-to-date overview of turbulent flow research in the areas of simulation and modeling. A key element of the book is the systematic, rational development of turbulence closure models and related aspects of modern turbulent flow theory and prediction. Starting with a review of the spectral dynamics of homogenous and inhomogeneous turbulent flows, succeeding chapters deal with numerical simulation techniques, renormalization group methods and turbulent closure modeling. Each chapter is authored by recognized leaders in their respective fields, and each provides a thorough and cohesive treatment of the subject.
Direct and Large-Eddy Simulation II

Book Description
Reports recent developments in the direct numerical simulation and large-eddy simulation of turbulence from Europe and Japan. The 40 papers cover jets, sub-grid models and homogeneous turbulence, separated flows and transition, thermal and compressible flows, wall flows and channel flows, complex flows, reacting flows, combustion, and flow past a square cylinder as a test case for large-eddy simulation 2. Among the specific topics are amplified frequencies in the proximal region of a circular jet, the self-consistency of the Smagorinsky constant and the value of the Rotta parameter at high Reynolds numbers, the large-eddy simulation of separated boundary layer transition, pressure and dilatation effects in high-speed turbulence, the mechanism of attenuation of turbulence by spanwise wall oscillation, non-unique solutions in turbulent curved pipe flow, extending the dynamic modelling procedure to turbulent reacting flows, and the large-eddy simulation of flow past a square cylinder using embedded meshes.

Book Description
obtained are still severely limited to low Reynolds numbers (about only one decade better than direct numerical simulations), and the interpretation of such calculations for complex, curved geometries is still unclear. It is evident that a lot of work (and a very significant increase in available computing power) is required before such methods can be adopted in daily's engineering practice. I hope to l"Cport on all these topics in a near future. The book is divided into six chapters, each· chapter in subchapters, sections and subsections. The first part is introduced by Chapter 1 which summarizes the equations of fluid mechanies, it is developed in C~apters 2 to 4 devoted to the construction of turbulence models. What has been called "engineering methods" is considered in Chapter 2 where the Reynolds averaged equations al"C established and the closure problem studied (§1-3). A first detailed study of homogeneous turbulent flows follows (§4). It includes a review of available experimental data and their modeling. The eddy viscosity concept is analyzed in §5 with the l"Csulting ~alar-transport equation models such as the famous K-e model. Reynolds stl"Css models (Chapter 4) require a preliminary consideration of two-point turbulence concepts which are developed in Chapter 3 devoted to homogeneous turbulence. We review the two-point moments of velocity fields and their spectral transforms (§ 1), their general dynamics (§2) with the particular case of homogeneous, isotropie turbulence (§3) whel"C the so-called Kolmogorov's assumptions are discussed at length.
