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.

The European Turbulence Conferences have been organized under the auspices of the European Mechanics Committee (Euromech) to provide a forum for discussion and exchange of recent and new results in the field of turbulence. The first conference was organized in Lyon in 1986 with 152 participants. The second and third conferences were held in Berlin (1988) and Stockholm (1990) with 165 and 172 participants respectively. The fourth was organized in Delft from 30 June to 3 July 1992 by the J.M. Burgers Centre. There were 214 participants from 22 countries. This steadily growing number of participants demonstrates both the success and need for this type of conference. The main topics of the Fourth European Turbulence Conference were: Dynamical Systems and Transition; Statistical Physics and Turbulence; Experiments and Novel Experimental Techniques; Particles and Bubbles in Turbulence; Simulation Methods; Coherent Structures; Turbulence Modelling and Compressibility Effects. In addition a special session was held on the subject of CeBular Automata. Each of the sessions was introduced with a survey lecture. The lecturers were: W. Eckhaus, AJ. Libchaber, L. Katgerman, F. Durst, M. Lesieur, B. Legras, D.G. Dritschel and P. Bradshaw. The contributions of the participants were subdivided into oral and poster presentations. In addition to the normal program, some Speciai Interest Groups of Ercoftac (European Research Community on Flow, Turbulence and Combustion) presented their research activities in the form of a poster.
