Book Description

The purpose of this book is to provide a fairly broad treatment of the fluid
mechanics of turbomachinery. Emphasis is placed on the more utilitarian
equipment, such as compressors, blowers, fans, and pumps, that will be
encountered by most mechanical engineers as they pursue careers in industry.
This emphasis is intended to allow the text to serve as a useful reference or
review book for the practicing engineer. Both gas and hydraulic turbines are
considered for completeness, and the text inevitably includes material from
the large literature on gas turbine engines. These machines traditionally have
been treated as aerospace equipment and are considered at length in the liter-
ature (Oates, 1984; Wilson, 1984; Oates, 1985; Bathie, 1996; Lakshiminarayana,
1996; Mattingly, 1996).Although recent developments in power generation for
either load-peaking, distributed generation or process cogeneration have sig-
nificantly increased the chances that an engineering graduate will encounter
gas turbine engines, this text will focus primarily on the more commonly
encountered industrial equipment.
The performance parameters of fluid machinery are carefully developed
and illustrated through extensive examples. The relationship of the inherent
performance of a machine, in terms of the flow rate, head change, and sound
power or noise generation through the rotating impeller, is discussed and
treated as it relates to the fluid system with which the machine interacts.
The dependence of machine performance on the resistance characteristics of
the fluid system is emphasized throughout by examining the machine and the
system simultaneously through the text. The characteristic sound pressure
and sound power levels associated with a fluid machine are treated in this
text as a basic performance variable—along with flow and pressure change.
The fundamental relationship between the shape and internal geometry
of a turbomachine impeller and its inherent performance is treated from the
beginning of the text. In the early chapters, the shape and size of a machine
are related through the concepts of similarity parameters to show how the
head and the flow combine with shape and size to yield unique relationships
between the geometry and performance. The development of these “specific”
speed, noise, and size relations is set out in an empirical, traditional manner
as correlations of experimental data. The concepts are used to achieve a basic
unification of the very broad range and variety of machine types, shapes, and
sizes encountered in engineering practice.
