These proceedings contain the papers presented at the 4th International Symposium on Engineering Turbulence Modelling and Measurements held at Ajaccio, Corsica, France from 24-26 May 1999. It follows three previous conferences on the topic of engineering turbulence modelling and measurements. The purpose of this series of symposia is to provide a forum for presenting and discussing new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. Turbulence is still one of the key issues in tackling engineering flow problems. As powerful computers and accurate numerical methods are now available for solving the flow equations, and since engineering applications nearly always involve turbulence effects, the reliability of CFD analysis depends more and more on the performance of the turbulence models. Successful simulation of turbulence requires the understanding of the complex physical phenomena involved and suitable models for describing the turbulent momentum, heat and mass transfer. For the understanding of turbulence phenomena, experiments are indispensable, but they are equally important for providing data for the development and testing of turbulence models and hence for CFD software validation.

This timely book investigates the experiences of employees at all levels of Boeing Commercial Airplanes (BCA) during a ten-year period of dramatic organizational change. As Boeing transformed itself, workers and managers contended with repeated downsizing, shifting corporate culture, new roles for women, outsourcing, mergers, lean production, and rampant technological change. Drawing on a unique blend of quantitative and qualitative research, the authors consider how management strategies affected the well-being of Boeing employees, as well as their attitudes toward their jobs and their company. Boeing employees’ experience holds vital lessons for other employees, the leaders of other firms determined to thrive in today’s era of inescapable and growing global competition, as well as public officials concerned about the well-being of American workers and companies.

Reclaim your joy and thrive through the storms of life when you find your strength in God. The human soul has a built-in yearning for joy and beauty and all good things. But that craving for life is so easily lost in the pace and demands of modern life. Join New York Times bestselling author John Eldredge as he gives you the tools you need to follow Jesus' path of supernatural resilience. Between false promises of ease and comfort on one side and the sheer busyness and stress of daily life on the other, people today are facing a shortage of peace, happiness, and strength. In Resilient, Eldredge reveals a path toward genuine recovery and resilience through Jesus himself. Drawing on wisdom from Scripture and Christian tradition, and illustrated throughout with powerful, true stories of grit and survival, Resilient will help you: Tap into the river of life that God promises his people Learn to be patient with yourself--genuine recovery from spiritual and emotional trauma takes time and intentionality Create a plan to foster resilience in your day-to-day life Discover deep wells of freedom and strength through Christ who lives within us Thriving requires a resilient soul. This book will help you find the resilience you long for when the world has gone mad--and discover in Jesus himself the strength that prevails.

The combustion of fossil fuels remains a key technology for the foreseeable future. It is therefore important that we understand the mechanisms of combustion and, in particular, the role of turbulence within this process. Combustion always takes place within a turbulent flow field for two reasons: turbulence increases the mixing process and enhances combustion, but at the same time combustion releases heat which generates flow instability through buoyancy, thus enhancing the transition to turbulence. The four chapters of this book present a thorough introduction to the field of turbulent combustion. After an overview of modeling approaches, the three remaining chapters consider the three distinct cases of premixed, non-premixed, and partially premixed combustion, respectively. This book will be of value to researchers and students of engineering and applied mathematics by demonstrating the current theories of turbulent combustion within a unified presentation of the field.

Across much of the industrialized world, rivers that were physically transformed and ecologically ruined to facilitate industrial and agricultural development are now the focus of restoration and rehabilitation efforts. River Futures discusses the emergence of this new era of river repair and documents a comprehensive biophysical framework for river science and management. The book considers what can be done to maximize prospects for improving river health while maintaining or enhancing the provision of ecosystem services over the next fifty to one-hundred years. It provides a holistic overview of considerations that underpin the use of science in river management, emphasizing cross-disciplinary understanding that builds on a landscape template. The book frames the development of integrative river science and its application to river rehabilitation programs develops a coherent set of guiding principles with which to approach integrative river science considers the application of cross-disciplinary thinking in river rehabilitation experiences from around the world examines the crossover between science and management, outlining issues that must be addressed to promote healthier river futures Case studies explore practical applications in different parts of the world, highlighting approaches to the use of integrative river science, measures of success, and steps that could be taken to improve performance in future efforts. River Futures offers a positive, practical, and constructive focus that directly addresses the major challenge of a new era of river conservation and rehabilitation—that of bringing together the diverse and typically discipline-bound sets of knowledge and practices that are involved in repairing rivers. It is a valuable resource for anyone involved in river restoration and management, including restorationists, scientists, managers, and policymakers, as well as undergraduate and graduate students.

This book offers a unique multidisciplinary integration of the physics of turbulence and remote sensing technology. Remote Sensing of Turbulence provides a new vision on the research of turbulence and summarizes the current and future challenges of monitoring turbulence remotely. The book emphasizes sophisticated geophysical applications, detection, and recognition of complex turbulent flows in oceans and the atmosphere. Through several techniques based on microwave and optical/IR observations, the text explores the technological capabilities and tools for the detection of turbulence, their signatures, and variability. FEATURES Covers the fundamental aspects of turbulence problems with a broad geophysical scope for a wide audience of readers Provides a complete description of remote-sensing capabilities for observing turbulence in the earth’s environment Establishes the state-of-the-art remote-sensing techniques and methods of data analysis for turbulence detection Investigates and evaluates turbulence detection signatures, their properties, and variability Provides cutting-edge remote-sensing applications for space-based monitoring and forecasts of turbulence in oceans and the atmosphere This book is a great resource for applied physicists, the professional remote sensing community, ecologists, geophysicists, and earth scientists.
