Preface

This book is in fact the second edition of Fluid Machinery: Performance, Analysis and Design by Terry Wright. The subtitle change is thought to more adequately reflect the emphases of both the current work and the first edition. Unlike most books on the subject, which seem to emphasize only design of turbo machinery, at least half of the current work is dedicated to the more widespread engineering tasks of application of turbomachines and selection of the proper machine for a particular application.The preface to the first edition lays out the philosophy for the work in some detail and there is no need to repeat it here as there have been few changes.What has changed is the micro-organization of the material. There has been substantial reorganization within the chapters, hopefully allowing a more What has changed is the micro-organization of the material. There has been substantial reorganization within the chapters, hopefully allowing a more logical flow for the learner. It would be fair to say that the reader, be it a university student or a practicing engineer, has been at the front of our minds during this revision.A particularly vigorous effort has been made with the mathematical symbols, with the aim of keeping notation consistent within and across chapters.At times, this has required us to abandon customary usage in the field. Probably, the best example is the use of the vector-diagram angle β. Traditional use has β as the angle between the relative vector and the blade speed for radial flow machines and as the angle between the relative vector and the axial flow machines and as the angle between the relative vector and the axial (throughflow) direction in axial machines. We decided to keep β consistently as the relative velocity–speed angle in order to avoid confusion.As might be expected, we have updated the material where appropriate.This presents a particular challenge in the area of computational fluid dynamics (CFD) in turbomachinery. There has certainly been astounding growth in this field over the years since the first edition was published in 1999; how ever, even the leaders in this field state that a good design must begin with an  ever, even the leaders in this field state that a good design must begin with an essentially one-dimensional layout of the type that we emphasize. As a result,we only “point the way” toward using CFD for turbomachinery design and analysis A particularly strong feature of the book is the inclusion of a significant number of exercise problems at the end of the chapters. There are nearly 350 problems, with about a third of them new to this edition. A solutions manual is also available to instructors.
