The literature on cavitation chemistry is ripe with conjectures, possibilities, heuris tic arguments, and intelligent guesses. The chemical effects of cavitation have been explained by means of many theories, consisting of empirical constants, adjustable parameters, and the like. The chemists working with cavitation chemistry agree that the phenomenon is very complex and system specific. Mathematicians and physi cists have offered partial solutions to the observed phenomena on the basis of cavitation parameters, whereas chemists have attempted explanations based on the modes of reaction and the detection of intermediate chemical species. Nevertheless, no one has been able to formulate a unified theme, however crude, for its effects on the basis of the known parameters, such as cavitation and transient chemistry involving extremely high temperatures of nanosecond durations. When one surveys the literature on cavitation-assisted reactions, it is clear that the approach so far has been "Edisonian" in nature. While a large number of reactions have showed either enhanced yields or reduced reaction times, many reactions have remained unaffected in the presence of cavitation. The success or failure of cavitation reactions ultimately depends on the collapse of the cavity. Cavitation chemistry is based on the principles of the formation of small transient cavities, their growth and implosion, which produce chemical reactions caused by the generation of extreme pressures and temperatures and a high degree of micro turbulence.

Energy Aspects of Acoustic Cavitation and Sonochemistry: Fundamentals and Engineering covers topics ranging from fundamental modeling to up-scaled experiments. The book relates acoustic cavitation and its intrinsic energy balance to macroscopic physical and chemical events that are analyzed from an energetic perspective. Outcomes are directly projected into practical applications and technological assessments covering energy consumption, thermal dissipation, and energy efficiency of a diverse set of applications in mixed phase synthesis, environmental remediation and materials chemistry. Special interest is dedicated to the sonochemical production of hydrogen and its energetic dimensions. Due to the sensitive energy balance that governs this process, this is seen as a "green process" for the production of future energy carriers. Provides a concise and detailed description of energy conversion and exchange within the single acoustic cavitation bubble and bubble population, accompanying physical and chemical effects Features a comprehensive approach that is supported by experiments and the modeling of energy concentration within the sonochemical reactor, jointly with energy dissipation and damping phenomenon Gives a clear definition of energy efficiency metrics of industrial sono-processes and their application to the main emergent industrial fields harnessing acoustic cavitation and sonochemistry, notably for the production of hydrogen

This book will formally launch "organic synthesis engineering" as a distinctive field in the armory of the reaction engineer. Its main theme revolves around two developments: catalysis and the role of process intensification in enhancing overall productivity. Each of these two subjects are becoming increasingly useful in organic synthesis engineering, especially in the production of medium and small volume chemicals and enhancing reaction rates by extending laboratory techniques, such as ultrasound, phase transfer catalysts, membrane reactor, and microwaves, to industrial scale production. This volume describes the applications of catalysis in organic synthesis and outlines different techniques of reaction rate and/or selectivity enhancement against a background of reaction engineering principles for both homogeneous and heterogeneous systems.

The role of the chemical reactor is crucial for the industrial conversion of raw materials into products and numerous factors must be considered when selecting an appropriate and efficient chemical reactor. Chemical Reaction Engineering and Reactor Technology defines the qualitative aspects that affect the selection of an industrial chemical reactor and couples various reactor models to case-specific kinetic expressions for chemical processes. Thoroughly revised and updated, this much-anticipated Second Edition addresses the rapid academic and industrial development of chemical reaction engineering. Offering a systematic development of the chemical reaction engineering concept, this volume explores: essential stoichiometric, kinetic, and thermodynamic terms needed in the analysis of chemical reactors homogeneous and heterogeneous reactors reactor optimization aspects residence time distributions and non-ideal flow conditions in industrial reactors solutions of algebraic and ordinary differential equation systems gas- and liquid-phase diffusion coefficients and gas-film coefficients correlations for gas-liquid systems solubilities of gases in liquids guidelines for laboratory reactors and the estimation of kinetic parameters The authors pay special attention to the exact formulations and derivations of mass energy balances and their numerical solutions. Richly illustrated and containing exercises and solutions covering a number of processes, from oil refining to the development of specialty and fine chemicals, the text provides a clear understanding of chemical reactor analysis and design.

Cavitation is the process of formation of voids and clouds of bubbles in liquids under tension. Cavitation and the ability of liquids to withstand tension are therefore topics of considerable importance in a number of disciplines in pure and applied science. The monograph begins with a historical survey of early cavitation research which started with the pioneering work of F M L Donny and Marcelin Berthelot. The theoretical and experimental background to cavitation and the tensile strength of liquids - static and dynamic stressing of liquids and bubble studies - is then discussed before the practical consequences are considered. It is these 'applied' areas in which cavitation has most bearing on everyday life: engineers and marine architects must have an appreciation of the effects of cavitation on hydraulic machinery and ships' propellers while the cavitation properties of the liquid coolant can play a large part in the design and safety of fast nuclear reactors. In the medical field cavitation effects are met in joint cracking, decompression sickness and blood flow. The conclusion of the book, and a survey of the present state of knowledge, are presented by Professor H N V Temperley, who has had a lifetime's experience of cavitation research. This monograph will serve as a complete introduction to cavitation and tension in liquids for students of physics, engineering and chemical engineering. Researchers and teachers will find it a handy reference source. other_titles

Cavitation is the formation of voids or bubbles containing vapor and gas in an otherwise homogeneous fluid in regions where the pressure falls locally to that of the vapor pressure corresponding to ambient temperature. The regions of low pressure may be associated with either a high fluid velocity or vibration. Cavitation is an important factor in many areas of science, engineering, and occurs in many industrial processes. The book covers four general topic areas:1- The basic characteristics and physical mechanics of hydrodynamic cavitation,2- Cavitation damage from the viewpoint of both the hydrodynamic process and the reaction of particular materials.3- Cavitation study methods and equipment for research and performance testing.4- Cavitation effects in flow passages and hydraulic equipment and on fixed and free bodies.The book is intended as a combination of a reference book for those who work with cavitation, and as a monograph for advanced students interested in some of the basic problems associated with multi-phase flow. It is ideal for graduate students and research engineers and scientists.
