Axial Flow Fans: Design and Practice focuses on the design of axial flow fans and the practices involved in their applications. The manuscript first offers information on the fluid mechanics of ducted fans, boundary layer and skin friction relations, and aerofoil data for blade design. Discussions focus on flow deflection in cascade of aerofoils, pitching moment, lift, surface roughness in turbulent boundary layers, turbulent boundary layers in pressure gradients, laminar skin friction, viscosity and boundary layers, and similarity and non-dimensional numbers. The text then ponders on vortex flows in ducting and fan, ducts, and introduction to fan design methods. The book takes a look at the momentum and blade element considerations on free vortex flow of rotor and rotor losses. Topics include momentum considerations, profile drag, tip clearance losses, optimum conditions in terms of the flow and swirl coefficients, pressure relations and velocity vectors, and thrust and torque gradients. Tail fairing design and associated losses, overall efficiencies, torque, thrust, and power, and the design of fan unit with arbitrary vortex flow are also discussed. The publication is a dependable source of information for engineers and readers interested in the design of axial flow fans and practices involved in their operation.

The practical reference book and guide to fans, ventilation and ancillary equipment with a comprehensive buyers' guide to worldwide manufacturers and suppliers. Bill Cory, well-known throughout the fans and ventilation industry, has produced a comprehensive, practical reference with a broad scope: types of fans, how and why they work, ductwork, performance standards, testing, stressing, shafts and bearings. With advances in technology, manufacturers have had to continually improve the performance and efficiency of fans and ventilation systems; as a result, improvements that once seemed impossible have been achieved. Systems now range in all sizes, shapes, and weight, to match the ever increasing applications. An important reference in the wake of continuing harmonisation of standards throughout the European Union and the progression of National and International standards. The Handbook of Fans and Ventilation is a welcome aid to both mechanical and electrical engineers. This book will help you to... •Understand how and why fans work •Choose the appropriate fan for the right job, helping to save time and money •Learn installation, operational and maintenance techniques to keep your fans in perfect working order •Discover special fans for your unique requirements •Source the most appropriate equipment manufacturers for your individual needs - Helps you select, install, operate and maintain the appropriate fan for your application, to help you save time and money - Use as a reference tool, course-book, supplier guide or as a fan/ventilation selection system - Contains a guide to manufacturers and suppliers of ventilation systems, organised according to their different styles and basic principles of operation

Alluvial fans are gently sloping, fan-shaped landforms common at the base of mountain ranges in arid and semiarid regions such as the American West. Floods on alluvial fans, although characterized by relatively shallow depths, strike with little if any warning, can travel at extremely high velocities, and can carry a tremendous amount of sediment and debris. Such flooding presents unique problems to federal and state planners in terms of quantifying flood hazards, predicting the magnitude at which those hazards can be expected at a particular location, and devising reliable mitigation strategies. Alluvial Fan Flooding attempts to improve our capability to determine whether areas are subject to alluvial fan flooding and provides a practical perspective on how to make such a determination. The book presents criteria for determining whether an area is subject to flooding and provides examples of applying the definition and criteria to real situations in Arizona, California, New Mexico, Utah, and elsewhere. The volume also contains recommendations for the Federal Emergency Management Agency, which is primarily responsible for floodplain mapping, and for state and local decisionmakers involved in flood hazard reduction.

In Europe, thermoprocessing is the third largest energy consumption sector following traffic and room heating. Its structure is very much diversified and complex. Therefore it is split into a large number of subdivisions, each of them having a high importance for the industrial economy. Accordingly we find the application know-how for the design and the execution of respective equipment represented by a multitude of small but very specialized and significant companies and their experts. As a result there was only little chance to find a comprehensive survey of the practical side of this technology so far. This gap is now filled by the new "Handbook of Thermoprocessing Technologies" based on the contributions of many highly experienced, outstanding engineers working in this field. The main intention of this book is the presentation of practical thermal processing for the improvement of material and parts in industrial application. Additionally, a summary of respective thermal and material science fundamentals is given as well as basic fuel-related and electrical engineering knowledge for this technology and finally design aspects, components and safety requirements for the necessary heating installations are covered. In conclusion, a very wide and competent state of the art description is now available for all manufacturers and users of thermoprocessing equipment. But also specialists from neighbouring fields, students and all those who are generally interested in this important but widely unknown technology will find a quick survey here as well as a very profound expertise.

This textbook focuses on underground ventilation, addressing both theoretical and practical aspects. Readers will develop a deeper understanding of mine ventilation and adjacent areas of research. The content is clearly structured, moving through chapters in a pedagogical way. It begins by presenting an introduction to fluid mechanics, before discussing the environmental conditions in mines, underground fire management, and international legislation concerning mines. Particular attention is paid to development ends ventilation, an area that is underrepresented in scientific research. Each chapter includes a concise theoretical summary, followed by several worked-out examples, problems and questions to develop students’ skills. This textbook will be useful for undergraduate and master’s degree students around the world. In addition, the large number of practical cases included make it particularly well suited to preparing for professional engineer examinations and as a guide for practising engineers.
