INTRODUCTION 5

dynamical behaviour as obtained via linear and nonlinear analysis, putting the emphasis
on physical understanding.
Chapters 3 and 4 deal with the dynamics, mainly the stability, of straight (as opposed
to curved) pipes conveying fluid: both for the inherently conservative system (both ends
supported) and for the nonconservative one (e.g. when one end of the pipe is free).
The fundamentals of system behaviour are presented in Chapter 3 in terms of linear
theory, together with the pertinent experimental research. Chapter 4 treats some ‘less
usual’ systems: pipes sucking fluid, nonuniform pipes, parametric resoriances, and so on,
and also contains a section on applications. The nonlinear dynamics of the system, as
well as chaotic oscillations, are presented in Chapter 5, wherein may also be found an
introduction to the methods of modern nonlinear dynamics theory.
The ideas and methods developed and illustrated in Chapters 3-5 are of importance
throughout the rest of the book, since the fundamental dynamical behaviour of the systems
in the other chapters will be explained by analogy or reference to that presented in these
three chapters; hence, even if the reader has no special interest in the dynamics of pipes
conveying fluid, reading Chapter 3 is sine qua non for the proper understanding of the
rest of the book.
Chapter 6 deals with the dynamics of curved pipes conveying fluid, which, surprisingly
perhaps, is distinct from and analytically more complex than that of straight pipes.

1.4 CONTENTS OF VOLUME 2+
The pipes considered in Chapters 3-6 are sufficiently thick-walled to suppose that ideally,
their cross-section remains circular while in motion, so that the dynamics may be treated
via beam theory. In Chapter 7, thin-walled pipes are considered, which must be treated as
thin cylindrical shells. Turbulence-induced vibrations, as well as physiological applications
are discussed at the end of this chapter.
Chapters 8 and 9 deal with the dynamics of cylinders in axial flow: isolated cylinders
in unconfined or confined flow in Chapter 8, and cylinders in clusters in Chapter 9. The
stability and turbulence-induced vibrations of such systems are also discussed. Engineering
applications are also presented: e.g. submerged towed cylinders, and clustered cylinders
such as those used in nuclear reactor fuel bundles and tube-in-shell heat exchangers.
Chapter 10 deals with plates in axial flow.
Chapter 11 treats a special, technologically important, case of the material in Chapters 7
and 8: a single cylinder or shell in a rigid or flexible tube, subjected to annular flow in the
generally narrow passage in-between. This chapter also closes with discussion of some
engineering applications.
Chapter 12 presents in outline some topics involving axial flow not treated in detail in
this book, and Chapter 13 contains some general conclusions and remarks.

‘Volume 2 is scheduled to appear later, but soon after Volume 1.
