Turbulence in Mixing Operations: Theory and Application to Mixing and Reaction presents a summary of the current status of research on turbulent motion, mixing, and kinetics. Each chapter of this book discusses turbulence in the context of mixing and reaction in scalar fields. Chapters I and III discuss the classification of turbulent reacting systems and the different possibilities in this context. Chapter II reviews the properties of passive mixing. Chapter IV looks at turbulent mixing in chemically reactive flows. Chapter V uses different techniques to make parallel numerical calculations of both mixing and reaction. Finally, Chapter VI reviews turbulence and actual industrial mixing operations. This book will be of great value for chemical and industrial engineers, especially for those interested in turbulent and industrial mixing.

Mixing: Theory and Practice, Volume 1 focuses on the mechanisms and applications of mixing in turbulent flow. This book discusses the theoretical and empirical methods that provide a basis for predicting the process as well as the mechanical performance characteristics of equipment used in different types of mixing operations. Comprised of five chapters, this volume starts with an overview of the mixing process, which tends to reduce gradients or nonuniformities in properties, composition, or temperature of materials in bulk. This text then explores the mixing operations that involve the transfer of a component to or from an equipment surface or boundary. Other chapters discuss the kinds of problems that occur in the design and use of mixing equipment, including the selection of size, type, and operating conditions. The final chapter deals with heat transfer where agitation is provided by mechanical devices. Development, design, and operating engineers will find this book extremely useful.

Turbulent Mixing and Chemical Reactions Jerzy Ba???dyga, Warsaw University of Technology, Poland John R. Bourne, Visiting Professor, University of Birmingham, UK and Emeritus Professor, ETH Zurich, Switzerland The way in which reagents are mixed can greatly influence the yield and range of products formed by fast, multiple chemical reactions. Understanding this phenomenon enables chemists to carry out reactions more selectively, make better use of raw materials and simplify product workup and separation. Turbulent Mixing and Chemical Reactions presents a balanced treatment of the connection between mixing and reaction. It contains theoretical aspects, experimental methods and expected results as well as worked examples to illustrate problem solving. This book will be of interest to all scientists involved in chemical engineering, physical chemistry, and synthetic chemists in the fine chemical and pharmaceuticals industry.

Turbulence, mixing and the mutual interaction of turbulence and chemistry continue to remain perplexing and impregnable in the fron tiers of fluid mechanics. The past ten years have brought enormous advances in computers and computational techniques on the one hand and in measurements and data processing on the other. The impact of such capabilities has led to a revolution both in the understanding of the structure of turbulence as well as in the predictive methods for application in technology. The early ideas on turbulence being an array of complicated phenomena and having some form of reasonably strong coherent struc ture have become well substantiated in recent experimental work. We are still at the very beginning of understanding all of the aspects of such coherence and of the possibilities of incorporating such structure into the analytical models for even those cases where the thin shear layer approximation may be valid. Nevertheless a distinguished body of "eddy chasers" has come into existence. The structure of mixing layers which has been studied for some years in terms of correlations and spectral analysis is also getting better understood. Both probability concepts such as intermittency and conditional sampling as well as the concept of large scale structure and the associated strain seem to indicate possibilities of distinguishing and synthesizing 'engulfment' and molecular mixing.

Mixing may be thought of as the operation by which a system evolves from one state of simplicity (initial segregation) to another state of simplicity (complete uniformity). Between these two extremes, complex patterns emerge and die. Questions naturally arise- how can the geometry of complex patterns be characterised, what is the time scale of the process, what structures are involved in the flow? This volume, comprising the proceedings of the NATO ASI on Mixing, attempts to address these questions from the approaches of geometry, kinetics and structure. The ASI which brought together diverse communities with a common interest in the problem of mixing, now provides us with a comprehensive work on the problem of mixing.

This book describes the fundamentals of fast liquid-phase chemical reactions and the principles of their scientific foundation, technical implementation and industrial application of new technologies. In addition, the equipment required to perform these reactions, in a turbulent mode in the chemical, petrochemical and petroleum industries, is also discussed. The macrokinetic approach has been developed with consideration of the diffusion, hydrodynamics, and heat transfer processes. Due to the advancement of fundamental knowledge, equations of practical engineering importance have been obtained for the calculations of mass and heat transfer processes carried out in conditions of high turbulence, and developed for the implementation in fast chemical reactions involving the synthesis of low molecular weight products and polymers. New methods for controlling the molecular characteristics of polymers have been developed based on the tailored regulation of the hydrodynamics of the reactive mixture flow. Typical processes have been used as model examples to reveal the influence of turbulence on the behaviour of fast chemical reactions used for the synthesis of low molecular weight products, in single-phase and two-phase reactive systems. Brand new tubular devices have been developed with the following characteristics: compact size, high productivity, and a quasi-perfect mixing operation mode in turbulent flows. These devices are subdivided into cylindrical, shell-and-tube, 'zone', and diffuser-confusor designs. Original solutions are proposed for the instrumental implementation of fast liquid-phase processes and development of continuous energy- and resource-efficient technologies for the synthesis of some large-scale compounds.
