Wall bounded turbulent flows are of major importance in industrial and environmental fluid mechanics. The structure of the wall turbulence is intrinsically related to the coherent structures that play a fundamental role in the transport process. The comprehension of their regeneration mechanism is indispensable for the development of efficient strategies in terms of drag control and near wall turbulence management. This book provides an up-to-date overview on the progress made in this specific area in recent years.

Wall turbulence is encountered in many technological applicationsas well as in the atmosphere, and a detailed understanding leadingto its management would have considerable beneficial consequencesin many areas. A lot of inspired work by experimenters,theoreticians, engineers and mathematicians has been accomplishedover recent decades on this important topic and StatisticalApproach to Wall Turbulence provides an updated and integrated viewon the progress made in this area. Wall turbulence is a complex phenomenon that has several industrialapplications, such as in aerodynamics, turbomachinery, geophysicalflows, internal engines, etc. Several books exist on fluidturbulence, but Statistical Approach to Wall Turbulence is originalin the sense that it focuses solely on the turbulent flows boundedby solid boundaries. The book covers the different physical aspectsof wall turbulence, beginning with classical phenomenologicalaspects before advancing to recent research in the effects of theReynolds numbers, near wall coherent structures, and wall turbulenttransport process. This book would be of interest to postgraduate and undergraduatestudents in mechanical, chemical, and aerospace engineering, aswell as researchers in aerodynamics, combustion, and allapplications of wall turbulence.

This is an up-to-date review of recent advances in the study of two-phase flows, with focus on gas-liquid flows, liquid-liquid flows, and particle transport in turbulent flows. The book is divided into several chapters, which after introducing basic concepts lead the reader through a more complex treatment of the subjects. The reader will find an extensive review of both the older and the more recent literature, with abundance of formulas, correlations, graphs and tables. A comprehensive (though non exhaustive) list of bibliographic references is provided at the end of each chapter. The volume is especially indicated for researchers who would like to carry out experimental, theoretical or computational work on two-phase flows, as well as for professionals who wish to learn more about this topic.

This book - a sequel of previous publications 'Flows andChemical Reactions' and 'Chemical Reactions in Flows andHomogeneous Mixtures' - is devoted to flows with chemical reactionsin heterogeneous environments. Heterogeneous media in thisvolume include interfaces and lines. They may be the site ofradiation. Each type of flow is the subject of a chapter in thisvolume. We consider first, in Chapter 1, the question of the generationof environments biphasic individuals: dusty gas, mist, bubbleflow. Chapter 2 is devoted to the study at the mesoscopicscale: particle-fluid exchange of momentum and heat withdetermination of the respective exchange coefficients. In Chapter3, we establish simplified equations of macroscopic balance formass, for the momentum and energy, in the case of particles of onesize (monodisperse suspension). Radiative phenomena arepresented in Chapter 5.

This book presents the fundamental principles of mechanics tore-establish the equations of Discrete Mechanics. It introducesphysics and thermodynamics associated to the physicalmodeling. The development and the complementarity of scienceslead to review today the old concepts that were the basis for thedevelopment of continuum mechanics. The differential geometry isused to review the conservation laws of mechanics. For instance,this formalism requires a different location of vector and scalarquantities in space. The equations of Discrete Mechanics form asystem of equations where the Helmholtz-Hodge decomposition playsan important role.

This book presents contributions to the 18th biannual symposium of the German Aerospace Aerodynamics Association (STAB). The individual chapters reflect ongoing research conducted by the STAB members in the field of numerical and experimental fluid mechanics and aerodynamics, mainly for (but not limited to) aerospace applications, and cover both nationally and EC-funded projects. By addressing a number of essential research subjects, together with their related physical and mathematics fundamentals, the book provides readers with a comprehensive overview of the current research work in the field, as well as its main challenges and new directions. Current work on e.g. high aspect-ratio and low aspect-ratio wings, bluff bodies, laminar flow control and transition, active flow control, hypersonic flows, aeroelasticity, aeroacoustics and biofluid mechanics is exhaustively discussed here.
