In this monogaph the author summarizes the most important points ha has learned during a career devoted to advanced fan and compressor research and development. Although all of this work was originally aimed at military aircraft engine applications, much of it is relevant to commercial aircraft engines and also to industrial and consumer-oriented turbomachinery. Guidance is given to the aerodynamic designer in ost aspects of the detail design of axial compressors, backed up with references which the reader can persue for a more comprehensive treatment of individual points. Practical and convenient design approaches are commanded wherever possible. The author believes that the simpliest approach which can be logically defended is usually the best one, unless a designer has a very good reason for escalating the level of complexity in any area.

This book provides a thorough description of an aerodynamic design and analysis systems for Axial-Flow Compressors. It describes the basic fluid dynamic and thermodynamic principles, empirical models and numerical methods used for the full range of procedures and analytical tools that an engineer needs for virtually any tupe of Axial-Flow Compressor, aerodynamic design or analysis activity. It reviews and evaluates several design strategies that have been recommended in the literature or which have been found to be effective. It gives a complete description of an actual working system, such that readers can implement all or part of the system. Engineers responsible for developing, maintaining of improving design and analysis systems can benefit greatly from this type of reference. The technology has become so complex and the role of computers so pervasive that about the only way this can be done today is to concentrate on a specific design and analysis system. The author provides practical methodology as well as the details needed to implement the suggested procedures.

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.

An off-design axial-flow compressor code is presented and is available from COSMIC for predicting the aerodynamic performance maps of fans and compressors. Steady axisymmetric flow is assumed and the aerodynamic solution reduces to solving the two-dimensional flow field in the meridional plane. A streamline curvature method is used for calculating this flow-field outside the blade rows. This code allows for bleed flows and the first five stators can be reset for each rotational speed, capabilities which are necessary for large multistage compressors. The accuracy of the off-design performance predictions depend upon the validity of the flow loss and deviation correlation models. These empirical correlations for the flow loss and deviation are used to model the real flow effects and the off-design code will compute through small reverse flow regions. The input to this off-design code is fully described and a user's example case for a two-stage fan is included with complete input and output data sets. Also, a comparison of the off-design code predictions with experimental data is included which generally shows good agreement. Schmidt, James F. Unspecified Center...

An introduction to the theory and engineering practice that underpins the component design and analysis of radial flow turbocompressors. Drawing upon an extensive theoretical background and years of practical experience, the authors provide descriptions of applications, concepts, component design, analysis tools, performance maps, flow stability, and structural integrity, with illustrative examples. Features wide coverage of all types of radial compressor over many applications unified by the consistent use of dimensional analysis. Discusses the methods needed to analyse the performance, flow, and mechanical integrity that underpin the design of efficient centrifugal compressors with good flow range and stability. Includes explanation of the design of all radial compressor components, including inlet guide vanes, impellers, diffusers, volutes, return channels, de-swirl vanes and side-streams. Suitable as a reference for advanced students of turbomachinery, and a perfect tool for practising mechanical and aerospace engineers already within the field and those just entering it.
