Éléments de turbulence
Author: Michel Prud'homme
Publisher: Presses inter Polytechnique
ISBN: 9782553014079
Category : Science
Languages : fr
Pages : 260
Book Description
L'étude de la turbulence constitue sans aucun doute la branche la plus complexe de la mécanique des fluides. L'ouvrage Eléments de turbulence propose un exposé complet du sujet tout en étant concis. Il vise à combler une lacune en présentant dans un texte unifié un ensemble de concepts et d'équations que l'on trouve épars dans des traités ou des articles de périodique souvent inaccessibles pour les non-spécialistes. Le livre s'adresse en premier lieu aux étudiants des cycles supérieurs qui abordent cette discipline après avoir suivi un premier cours de mécanique des fluides. Les ingénieurs praticiens désirant parfaire leurs connaissances y trouveront également une source de renseignements très utile. Dans les deux premiers chapitres, l'auteur se penche sur la transition vers la turbulence, les échelles, l'approche statistique et les hypothèses de fermeture courantes. Les chapitres suivants traitent des solutions de similitude classiques des équations de transport en conduite et en écoulement libre, du raccordement des profils entre les régions de la paroi et du défaut de vitesse, de la turbulence homogène, de l'approche spectrale et des méthodes expérimentales. Outre la présentation théorique, l'ouvrage comporte de nombreux graphiques et illustrations, douze exercices et soixante-quatorze problèmes. [Source : 4e de couv.]

Analyses of Turbulence in the Neutrally and Stably Stratified Planetary Boundary Layer
Author: Cedrick Ansorge
Publisher: Springer
ISBN: 3319450441
Category : Science
Languages : en
Pages : 180
Book Description
This thesis presents a study of strong stratification and turbulence collapse in the planetary boundary layer, opening a new avenue in this field. It is the first work to study all regimes of stratified turbulence in a unified simulation framework without a break in the paradigms for representation of turbulence. To date, advances in our understanding and the parameterization of turbulence in the stable boundary layer have been hampered by difficulties simulating the strongly stratified regime, and the analysis has primarily been based on field measurements. The content presented here changes that paradigm by demonstrating the ability of direct numerical simulation to address this problem, and by doing so to remove the uncertainty of turbulence models from the analysis. Employing a stably stratified Ekman layer as a simplified physical model of the stable boundary layer, the three stratification regimes observed in nature— weakly, intermediately and strongly stratified—are reproduced, and the data is subsequently used to answer key, long-standing questions. The main part of the book is organized in three sections, namely a comprehensive introduction, numerics, and physics. The thesis ends with a clear and concise conclusion that distills specific implications for the study of the stable boundary layer. This structure emphasizes the physical results, but at the same time gives relevance to the technical aspects of numerical schemes and post-processing tools. The selection of the relevant literature during the introduction, and its use along the work appropriately combines literature from two research communities: fluid dynamics, and boundary-layer meteorology.

Book Description
La r duction de la tra n e est un ph nom ne d' coulement qui, par la pr sence de tr s petites quantit s d'additifs (polym res ou tensio-actifs) dans un fluide quelconque, consiste en une r duction significative du frottement la paroi en r gime turbulent. Certaines solutions d'additifs conduisent une r duction du frottement pouvant aller jusqu' 90 % par rapport au solvant pur. Ceci induit une r duction de la puissance de pompage de l'ordre de 30 %.

Constructive Modeling of Structural Turbulence and Hydrodynamic Instabilities
Author: Oleg Mikhailovich Belotserkovskii
Publisher: World Scientific
ISBN: 9812833021
Category : Science
Languages : en
Pages : 489
Book Description
The book provides an original approach in the research of structural analysis of free developed shear compressible turbulence at high Reynolds number on the base of direct numerical simulation (DNS) and instability evolution for ideal medium (integral conservation laws) with approximate mechanism of dissipation (FLUX dissipative monotone OC upwindOCO difference schemes) and does not use any explicit sub-grid approximation and semi-empirical models of turbulence. Convective mixing is considered as a principal part of conservation law.

Multiscale Turbulent Transport
Author: Marco Martins Afonso
Publisher: MDPI
ISBN: 3039282123
Category : Technology & Engineering
Languages : en
Pages : 210
Book Description
Turbulent transport is currently a prominent and ongoing investigation subject at the interface of methodologies from theory to numerical simulations and experiments, and it covers several spatiotemporal scales. Mathematical analysis, physical modelling, and engineering applications represent different facets of a classical, long-standing problem that is still far from being thoroughly comprehended. The goal of this Special Issue is to outline recent advances of such subjects as multiscale analysis in turbulent transport processes, Lagrangian and Eulerian descriptions of turbulence, advection of particles and fields in turbulent flows, ideal or nonideal turbulence (unstationary/inhomogeneous/anisotropic/compressible), turbulent flows in biofluid mechanics and magnetohydrodynamics, and the control and optimization of turbulent transport. The SI is open to regular articles, review papers focused on the state of the art and the progress made over the last few years, and new research trends.
