Description
Taylor & Francis Ltd Fluid Machinery 2010 Edition by Terry Wright, Philip Gerhart
Published nearly a decade ago, Fluid Machinery: Performance, Analysis, and Design quickly became popular with students, professors, and professionals because of its comprehensive and comprehensible introduction to the fluid mechanics of turbomachinery. Renamed to reflect its wider scope and reorganized content, this second edition provides a more logical flow of information that will enhance understanding. In particular, it presents a consistent notation within and across chapters, updating material when appropriate. Although the authors do account for the astounding growth in the field of computational fluid dynamics that has occurred since publication of the first edition, this text emphasizes traditional "one-dimensional" layout and points the way toward using CFD for turbomachinery design and analysis. Presents Extensive Examples and Design Exercises to Illustrate Performance Parameters and Machine GeometryBy focusing on the preliminary design and selection of equipment to meet performance specifications, the authors promote a basic yet thorough understanding of the subject. They cover topics including gas and hydraulic turbines and equipment that is widely used in the industry, such as compressors, blowers, fans, and pumps.This book promotes a pragmatic approach to turbomachinery application and design, examining a realistic array of difficulties and conflicting requirements. The authors use examples from a broad range of industrial applications to illustrate the generality of the basic design approach and the common ground of seemingly diverse areas of application.With a variety of illustrations, examples, and exercises that emphasize real-world industrial applications, this book not only prepares students to face industrial applications with confidence, but also supplies professionals with a compact and easy-to-use reference. 1 INTRODUCTION1.1 Preliminary Remarks1.2 Thermodynamics and Fluid Mechanics1.3 Units and Nomenclature1.4 Thermodynamic Variables and Properties1.5 Reversible Processes, Irreversible Processes and Efficiency With Perfect Gases1.6 Equations of Fluid Mechanics and Thermodynamics1.7 Turbomachines1.8 Classifications1.9 Turbomachine Performance and Rating1.10 Rating and Performance For Liquid Pumps1.11 Compressible Flow Machines1.12 Typical Performance Curves1.13 Machine and System2 DIMENSIONAL ANALYSIS AND SIMILARITY FOR TURBOMACHINERY2.1 Dimensionality2.2 Similitude2.3 Dimensionless Numbers and -Products2.4 Dimensionless Performance Variables and Similarity for Turbomachinery2.5 Compressible Flow Similarity2.6 Specific Speed and Specific Diameter2.7 Correlations of Machine Type and the Cordier Diagrams 3 SCALING LAWS, LIMITATIONS, AND CAVITATION3.1 Scaling of Performance3.2 Limitations and Corrections for Reynolds Number and Surface Roughness3.3 Compressibility (Mach Number) Limitations and Corrections3.4 Cavitation Avoidance in Pumps (and Turbines)4 TURBOMACHINERY NOISE4.1 Introductory Remarks4.2 Sound And Noise4.3 Fan Noise4.4 Sound Power and Sound Pressure4.5 Outdoor Propagation4.6 Indoor Propagation4.7 A Note on Pump Noise4.8 Compressor and Turbine Noise5 PERFORMANCE ESTIMATION, MACHINE SELECTION AND PRELIMINARY DESIGN5.1 Preliminary Remarks5.1 Cordier Diagram and Machine Type5.3 Estimating the Efficiency5.4 Preliminary Machine Selection 5.5 Fan Selection From Vendor Data5.6 Pump Selection From Vendor Data5.7 Selection of Variable Pitch And Variable Inlet Vane Fans 6 FUNDAMENTALS OF FLOW IN TURBOMACHINERY6.1 Preliminary Remarks6.2 Blade and Cascade Geometry6.3 Velocity Diagrams6.4 Energy (Work) Transfer In A Rotor6.5 Work, Head, Pressure, and Efficiency6.6 Preliminary Design of an Axial Fan6.7 Diffusion Considerations6.8 Diffusion Limits in Axial Flow Machines6.9 Preliminary Design and Diffusion Limits in Radial Flow7 VELOCITY DIAGRAMS AND FLOWPATH LAYOUT7.1 Preliminary Remarks7.2 Velocity Diagram Parameters For Axial Flow Machines7.3 Axial Flow Pumps, Fans, and Compressors7.4 Axial Flow Turbines7.5 Hub - Tip Variations For Axial Flow Machines7.6 Radial And Mixed Flow7.7 A Mixed Flow Example7.8 Radial Flow Layout : Centrifugal Blowers7.9 Radial Flow Layout : A Centrifugal Pump 7.10 Radial Flow Layout : Turbocharger Components7.11 Diffusers And Volutes7.12 Axial Flow Diffusers7.13 Radial Flow : Volute Diffusers8 TWO-DIMENSIONAL CASCADES8.1 One, Two, And Three Dimensional Flow Models8.2 Axial Flow Cascades : Basic Geometry and Simple Flow Models8.3 Systematic Investigation Axial Cascade Flow8.4 Correlations for Cascade Performance8.5 Blade Number and Low-Solidity Cascades8.6 Diffusion Limitations and Selection of Solidity 8.7 Losses in Diffusing Cascades8.8 Axial Flow Turbine Cascades8.9 Radial Flow Cascades8.10 Solidity Of Centrifugal Cascades9 QUASI-THREE-DIMENSIONAL FLOW9.1 The Quasi-Three-Dimensional Flow Model9.2 Simple Radial Equilibrium for Axial Flow Machines9.3 Approximate Solutions for Simple Radial Equilibrium9.4 Extension to Non-Uniform Inflow9.5 Quasi-Three-Dimensional Model For Centrifugal Machines9.6 Simpler Solutions10 ADVANCED TOPICS IN PERFORMANCE AND DESIGN10.1 Introduction10.2 Freestream Turbulence Intensity10.3 Secondary And Three-Dimensional Flow Effect10.4 Low Reynolds Number Effects In Axial Flow Cascades 10.5 Stall, Surge, And Loss Of Stability10.6 Computational Fluid Dynamics In TurbomachineryAppendices
