Accurately predicting the behaviour of multiphase flows is a problem of immense industrial and scientific interest. Modern computers can now study the dynamics in great detail and these simulations yield unprecedented insight. This book provides a comprehensive introduction to direct numerical simulations of multiphase flows for researchers and graduate students. After a brief overview of the context and history the authors review the governing equations. A particular emphasis is placed on the 'one-fluid' formulation where a single set of equations is used to describe the entire flow field and interface terms are included as singularity distributions. Several applications are discussed, showing how direct numerical simulations have helped researchers advance both our understanding and our ability to make predictions. The final chapter gives an overview of recent studies of flows with relatively complex physics, such as mass transfer and chemical reactions, solidification and boiling, and includes extensive references to current work.
Thanks to high-speed computers and advanced algorithms, the important field of modelling multiphase flows is an area of rapid growth. This one-stop account – now in paperback, with corrections from the first printing – is the ideal way to get to grips with this topic, which has significant applications in industry and nature. Each chapter is written by an acknowledged expert and includes extensive references to current research. All of the chapters are essentially independent and so the book can be used for a range of advanced courses and the self-study of specific topics. No other book covers so many topics related to multiphase flow, and it will therefore be warmly welcomed by researchers and graduate students of the subject across engineering, physics, and applied mathematics.
"Engineering education is currently on the verge of a major transformation. However, while the need has been much discussed and several proposals for change have been put forward, relatively little focus has been put on actual implementation of the proposed changes. This book examines a program that has a long history of experimentation in engineering education. Written by experts on the subject, it describes specific topics with each chapter focusing on a specific innovation that has been carried out and explaining the educational pedagogy the learning benefit, as well as the transferability of the approach"--
A look at engineering education today— with an eye to tomorrow Engineering education is in flux. While it is increasingly important that engineers be innovative, entrepreneurial, collaborative, and able to work globally, there are virtually no programs that prepare students to meet these new challenges. Shaping Our World: Engineering Education for the 21st Century seeks to fill this void, exploring revolutionary approaches to the current engineering curriculum that will bring it fully up to date and prepare the next generation of would-be engineers for real and lasting professional success. Comprised of fourteen chapters written by respected experts on engineering education, the book is di...

Many of the significant issues in fluid dynamics occur at interfaces, that is, at the boundaries between differing fluids or between fluids and solids. These issues are important in areas ranging from aircraft flight, to the flow of blood in the heart, to chemical vapour deposition. The subject is an area of active research and development, owing to improved analytical, experimental, and computational techniques. This book describes research and applications in interfacial fluid dynamics and stability. It is organized around five topics: Benard and thermocapillary instabilities, shear and pressure induced instabilities, waves and dispersions, multiphase systems, and complex flows. Chapters have been contributed by internationally recognized experts, both theoreticians and experimentalists. Because of the range and importance of topics discussed, this book will interest a broad audience of graduate students and researchers in mechanical, aerospace, materials, and chemical engineering, as well as in applied mathematics and physics.
