This book is a description of why and how to do Scientific
Computing for fundamental models of fluid flow. It contains
introduction, motivation, analysis, and algorithms and is closely
tied to freely available MATLAB codes that implement the methods
described. The focus is on finite element approximation methods and
fast iterative solution methods for the consequent linear(ized)
systems arising in important problems that model incompressible
fluid flow. The problems addressed are the Poisson equation,
Convection-Diffusion problem, Stokes problem and Navier-Stokes
problem, including new material on time-dependent problems and
models of multi-physics. The corresponding iterative algebra based
on preconditioned Krylov subspace and multigrid techniques is for
symmetric and positive definite, nonsymmetric positive definite,
symmetric indefinite and nonsymmetric indefinite matrix systems
respectively. For each problem and associated solvers there is a
description of how to compute together with theoretical analysis
that guides the choice of approaches and describes what happens in
practice in the many illustrative numerical results throughout the
book (computed with the freely downloadable IFISS software). All of
the numerical results should be reproducible by readers who have
access to MATLAB and there is considerable scope for
experimentation in the "computational laboratory " provided by the
software. Developments in the field since the first edition was
published have been represented in three new chapters covering
optimization with PDE constraints (Chapter 5); solution of unsteady
Navier-Stokes equations (Chapter 10); solution of models of
buoyancy-driven flow (Chapter 11). Each chapter has many
theoretical problems and practical computer exercises that involve
the use of the IFISS software. This book is suitable as an
introduction to iterative linear solvers or more generally as a
model of Scientific Computing at an advanced undergraduate or
beginning graduate level.
This is the second volume in a four-part series on fluid dynamics:
Part 1. Classical Fluid Dynamics Part 2. Asymptotic Problems of
Fluid Dynamics Part 3. Boundary Layers Part 4. Hydrodynamic
Stability Theory The series is designed to give a comprehensive and
coherent description of fluid dynamics, starting with chapters on
classical theory suitable for an introductory undergraduate lecture
course, and then progressing through more advanced material up to
the level of modern research in the field. In Part 2 the reader is
introduced to asymptotic methods, and their applications to fluid
dynamics. Firstly, it discusses the mathematical aspects of the
asymptotic theory. This is followed by an exposition of the results
of inviscid flow theory, starting with subsonic flows past thin
aerofoils. This includes unsteady flow theory and the analysis of
separated flows. The authors then consider supersonic flow past a
thin aerofoil, where the linear approximation leads to the Ackeret
formula for the pressure. They also discuss the second order
Buzemann approximation, and the flow behaviour at large distances
from the aerofoil. Then the properties of transonic and hypersonic
flows are examined in detail. Part 2 concludes with a discussion of
viscous low-Reynolds-number flows. Two classical problems of the
low-Reynolds-number flow theory are considered, the flow past a
sphere and the flow past a circular cylinder. In both cases the
flow analysis leads to a difficulty, known as Stokes paradox. The
authors show that this paradox can be resolved using the formalism
of matched asymptotic expansions.
Who Needs Nuclear Power challenges conventional thinking about the
role of civil nuclear power in a rapidly changing energy context,
where new energy carriers are penetrating markets around the world.
Against the backdrop of a global energy transition and the defining
issue of Climate Change, Chris Anastasi assesses new nuclear build
in a fast-moving sector in which new technologies and practices are
rapidly emerging. He considers various countries at different
stages of nuclear industry development, and discusses their
political, legal and technical institutions that provide the
framework for both existing nuclear facilities and new build, as
well as a country's technical capability. He also highlights the
critical issue of nuclear safety culture, exploring how
organisations go about instilling it and maintaining it in their
operations and encouraging it in their supply chains; the critical
role played by independent regulators and international
institutions in ensuring the integrity of the industry is also
highlighted. This book provides a balanced and holistic view of
nuclear power for both an expert and non-expert audience, and a
realistic assessment of the potential for this technology over the
critical period to 2050 and beyond.
This book reviews basic electromagnetic (EM) wave theory and
applies it specifically to lasers in order to give the reader not
only tangible examples of how the theory is manifested in real
life, but also practical knowledge about lasers, and their
operation and usage. The latter can be useful for those involved
with using lasers. As a short treatise on this subject matter, this
book is not intended to dwell deeply into the details of EM waves
nor lasers. A bibliography is provided for those who wish to
explore in more depth the topics covered in this book. Rather the
aim of this book is to offer a quick overview, which will allow the
reader to gain a competent general understanding of EM waves and
lasers.
Externally tunable properties allow for new applications of
magnetic hybrid materials containing magnetic micro- and
nanoparticles in sensors and actuators in technical and medical
applications. By means of easy to generate and control magnetic
fields, changes of the internal particle arrangements and the
macroscopic properties can be achieved. This monograph delivers the
latest insights into multi-scale modelling, experimental
characterization, manufacturing and application of those magnetic
hybrid materials.
Fluid mechanics is the study of how fluids behave and interact
under various forces and in various applied situations, whether in
liquid or gas state or both. The author compiles pertinent
information that are introduced in the more advanced classes at the
senior level and at the graduate level. "Advanced Fluid Mechanics"
courses typically cover a variety of topics involving fluids in
various multiple states (phases), with both elastic and non-elastic
qualities, and flowing in complex ways. This new text will
integrate both the simple stages of fluid mechanics
("Fundamentals") with those involving more complex parameters,
including Inviscid Flow in multi-dimensions, Viscous Flow and
Turbulence, and a succinct introduction to Computational Fluid
Dynamics. It will offer exceptional pedagogy, for both classroom
use and self-instruction, including many worked-out examples,
end-of-chapter problems, and actual computer programs that can be
used to reinforce theory with real-world applications.
Professional engineers as well as Physicists and Chemists working
in the analysis of fluid behavior in complex systems will find the
contents of this book useful.All manufacturing companies involved
in any sort of systems that encompass fluids and fluid flow
analysis (e.g., heat exchangers, air conditioning and
refrigeration, chemical processes, etc.) or energy generation
(steam boilers, turbines and internal combustion engines, jet
propulsion systems, etc.), or fluid systems and fluid power (e.g.,
hydraulics, piping systems, and so on)will reap the benefits of
this text.

Integrable models have a fascinating history with many important
discoveries that dates back to the famous Kepler problem of
planetary motion. Nowadays it is well recognised that integrable
systems play a ubiquitous role in many research areas ranging from
quantum field theory, string theory, solvable models of statistical
mechanics, black hole physics, quantum chaos and the AdS/CFT
correspondence, to pure mathematics, such as representation theory,
harmonic analysis, random matrix theory and complex geometry.
Starting with the Liouville theorem and finite-dimensional
integrable models, this book covers the basic concepts of
integrability including elements of the modern geometric approach
based on Poisson reduction, classical and quantum factorised
scattering and various incarnations of the Bethe Ansatz.
Applications of integrability methods are illustrated in vast
detail on the concrete examples of the Calogero-Moser-Sutherland
and Ruijsenaars-Schneider models, the Heisenberg spin chain and the
one-dimensional Bose gas interacting via a delta-function
potential. This book has intermediate and advanced topics with
details to make them clearly comprehensible.
This introductory text emphasises physical principles, rather than
the mathematics. Each topic begins with a discussion of the
physical characteristics of the motion or system. The mathematics
is kept as clear as possible, and includes elegant mathematical
descriptions where possible. Designed to provide a logical
development of the subject, the book is divided into two sections,
vibrations followed by waves. A particular feature is the inclusion
of many examples, frequently drawn from everyday life, along with
more cutting-edge ones. Each chapter includes problems ranging in
difficulty from simple to challenging and includes hints for
solving problems. Numerous worked examples included throughout the
book.
