Man-made or industrial processes, localised or geographically
distributed, need be automated in order to ensure they produce
quality, consistent, and cost-effective goods or services.
Automation systems for these processes broadly consist of
instrumentation, control, human interface, and communication
subsystems. This book introduces the basics of philosophy,
technology, terminology, and practices of modern automation systems
with simple illustrations and examples.
Aerodynamics is a science that improves the ability to understand
theoretical basics and apply fundamental physics in real-life
problems. The study of the motion of air, both externally over an
airplane wing and internally over a scramjet engine intake, has
acknowledged the significance of studying both incompressible and
compressible flow aerodynamics. Aspects and Applications of
Incompressible and Compressible Aerodynamics discusses all aspects
of aerodynamics from application to theory. It further presents the
equations and mathematical models used to describe and characterize
flow fields as well as their thermodynamic aspects and
applications. Covering topics such as airplane configurations,
hypersonic vehicles, and the parametric effect of roughness, this
premier reference source is an essential resource for engineers,
scientists, students and educators of higher education, military
experts, libraries, government officials, researchers, and
academicians.
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.
The complete reference for engineers and designers working on pump
design and development, or using centrifugal pumps in the field.
This authoritative guide has been developed with access to the
technical expertise of the leading centrifugal pump developer,
Sulzer. In addition to providing the most comprehensive centrifugal
pump theory and design reference, with detailed material on
cavitation, erosion, selection of materials, rotor vibration
behaviour and forces acting on pumps, the Handbook also covers key
pumping applications topics and operational issues including
operating performance in various types of circuitry, drives and
acceptance testing.
* Enables readers to understand, specify and utilise centrifugal
pumps more effectively
* A complete centrifugal pump engineering guide. The Handbook
covers theory, design and operation, with an emphasis on providing
a high levels of rigorous data, design detail, and industry-leading
quality and efficiency solutions for high capital outlay pump plant
users.
* Draws on the world-beating experience of Sulzer, the leading
centrifugal pump developer, making this a particularly valuable
resource
* Third edition, updated to cover the latest design and technology
developments, applications, test and reliability procedures,
cavitation, erosion, selection of materials, rotor vibration
behaviour, operating performance in various types of circuitry, new
drive technology and acceptance testing.
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.
Topics of this book span the range from spatial and temporal
discretization techniques for contact and impact problems with
small and finite deformations over investigations on the
reliability of micromechanical contact models over emerging
techniques for rolling contact mechanics to homogenization methods
and multi-scale approaches in contact problems.
