Centrifugal Compressors


Book Description

A mechanical engineer with a Pennsylvania turbomachinery company, A ungier describes his own system and strategy for designing and analyzing centrifugal compressor aerodynamics. To address the novice as well as the experienced in the field, he presents the basic thermodynamic and fluid dynamic principles, empirical models, and key numerical methods that form the basis of his methods. His strategy, or design practice, he found harder to describe because it involves a process of reasoning rather than following an established set of principles. He recognizes that his is only one of many possible methods, but makes no effort to compare or contrast his with any other.

Axial-flow Compressors


Book Description

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.




Design of Radial Turbomachines


Book Description

During the past three decades advances have been made in the fluid dynamic and thermodynamic design and understanding of radial flow turbomachines. Radial turbomachines possess their own distinctive characteristics, and present the engineer with as full a range of complexities as any fluid flow problem. This book describes the current technology and design methods for centrifugal compressors and radial turbines working in compressible flow. These are of particular relevance to gas turbine engines, internal combustion engine turbochargers, process compressors and cryogenic expanders. The aerodynamic design of the turbomachine is preliminary design to the specification of blade forms and computational fluid dynamic analysis of vane and blade passage flows. The treatment throughout is modern, with full recognition of current computer-aided design methods. However throughout the book a clear separation is made between the fundamental gas dynamics and the empiricism necessary to close the gap between theory and practice in situations of such complexity. Computer program listings for preliminary design are included. The problems posed by specific applications are dealt with in details: for example, techniques for the suppression of surge in centrifugal compressors and a consequent widening of the operating range, and the problems of pulse operation of radial turbines as encountered in turbocharger applications. The book contains comprehensive surveys of the literature in all these fields.
