Book Description
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.

Book Description
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

Book Description
It is emphasized that, if noise reductions are to be obtained or if present noise levels are to be maintained for higher power ratings, future propeller designs should operate at lower tip Mach numbers are currently being used. Single- rather than dual-rotating propellers were found to generate the lowest over-all noise levels for a given number of blades.

Book Description
This book gathers the latest advances, innovations, and applications in the field of innovative biosystems engineering for sustainable agriculture, forestry and food production. Focusing on the challenges of implementing sustainability in various contexts in the fields of biosystems engineering, it shows how the research has addressed the sustainable use of renewable and non-renewable resources. It also presents possible solutions to help achieve sustainable production. The Mid-Term Conference of the Italian Association of Agricultural Engineering (AIIA) is part of a series of conferences, seminars and meetings that the AIIA organizes, together with other public and private stakeholders, to promote the creation and dissemination of new knowledge in the sector. The contributions included in the book were selected by means of a rigorous peer-review process, and offer an extensive and multidisciplinary overview of interesting solutions in the field of innovative biosystems engineering for sustainable agriculture.
