Experimental Hydrodynamics for Flow around Bodies explains complex
novel experimental methodologies to solve a wide range of important
flow problems in industry and research. The book starts by
examining the fundamental physical laws necessary for the
optimization of techniques for hydro-aeromechanics, heat
engineering, and other disciplines related to flow. The reader is
then provided with detailed explanations of novel experimental
methods, along with the results of physical research. These results
are also necessary for the construction of theoretical models that
provide improved descriptions for numerous problems in various
scientific fields. Frequent discussions, examples of practical
applications throughout the text, and foundational, theoretical
materials help a range of readers engage and apply these methods to
problems in fields including drag reduction, noiseless movement,
optimal maneuvering, intense heat transfer, control of separated
vortices, wind power, economical energy consumption, and more.
Liutex and Its Applications in Turbulence Research reviews the
history of vortex definition, provides an accurate mathematical
definition of vortices, and explains their applications in flow
transition, turbulent flow, flow control, and turbulent flow
experiments. The book explains the term "Rortex" as a
mathematically defined rigid rotation of fluids or vortex, which
could help solve many longstanding problems in turbulence research.
The accurate mathematical definition of the vortex is important in
a range of industrial contexts, including aerospace, turbine
machinery, combustion, and electronic cooling systems, so there are
many areas of research that can benefit from the innovations
described here. This book provides a thorough survey of the latest
research in generalized and flow-thermal, unified, law-of-the-wall
for wall-bounded turbulence. Important theory and methodologies
used for developing these laws are described in detail, including:
the classification of the conventional turbulent boundary layer
concept based on proper velocity scaling; the methodology for
identification of the scales of velocity, temperature, and length
needed to establish the law; and the discovery, proof, and strict
validations of the laws, with both Reynolds and Prandtl number
independency properties using DNS data. The establishment of these
statistical laws is important to modern fluid mechanics and heat
transfer research, and greatly expands our understanding of
wall-bounded turbulence.
Extremum Seeking through Delays and PDEs, the first book on the
topic, expands the scope of applicability of the extremum seeking
method, from static and finite-dimensional systems to
infinite-dimensional systems. Readers will find: Numerous
algorithms for model-free real-time optimization are developed and
their convergence guaranteed. Extensions from single-player
optimization to noncooperative games, under delays and pdes, are
provided. The delays and pdes are compensated in the control
designs using the pde backstepping approach, and stability is
ensured using infinite-dimensional versions of averaging theory.
Accessible and powerful tools for analysis. This book is intended
for control engineers in all disciplines (electrical, mechanical,
aerospace, chemical), mathematicians, physicists, biologists, and
economists. It is appropriate for graduate students, researchers,
and industrial users.
A world-recognized expert in the science of vehicle dynamics, Dr.
Thomas Gillespie has created an ideal reference book that has been
used by engineers for 30 years, ranging from an introduction to the
subject at the university level to a common sight on the desks of
engineers throughout the world. As with the original printing,
Fundamentals of Vehicle Dynamics, Revised Edition, strives to find
a middle ground by balancing the need to provide detailed
conceptual explanations of the engineering principles involved in
the dynamics of ground vehicles with equations and example problems
that clearly and concisely demonstrate how to apply such
principles. A study of this book will ensure that the reader comes
away with a solid foundation and is prepared to discuss the subject
in detail. Ideal as much for a first course in vehicle dynamics as
it is a professional reference, Fundamentals of Vehicle Dynamics,
Revised Edition, maintains the tradition of the original by being
easy to read and while receiving updates throughout in the form of
modernized graphics and improved readability.
The Mechanics of Inhaled Pharmaceutical Aerosols: An Introduction,
Second Edition provides a concise, but thorough exposition of
fundamental concepts in the field of pharmaceutical aerosols. This
revised edition will allow researchers in the field to gain a
thorough understanding of the field from first principles, allowing
them to understand, design, develop and improve inhaled
pharmaceutical aerosol devices and therapies. Chapters consider
mechanics and deposition, specifically in the respiratory tract,
while others discuss the mechanics associated with the three
existing types of pharmaceutical inhalation devices. This text will
be very useful for academics and for courses taught at both
undergraduate and graduate levels. Because of the interdisciplinary
nature of this book, it will also serve a wide audience that
includes engineers and scientists involved with inhaled aerosol
therapies.
Acoustics: Sound Fields, Transducers and Vibration, Second Edition
guides readers through the basics of sound fields, the laws
governing sound generation, radiation, and propagation, and general
terminology. Specific sections cover microphones (electromagnetic,
electrostatic, and ribbon), earphones, and horns, loudspeaker
enclosures, baffles and transmission lines, miniature applications
(e.g. MEMS microphones and micro speakers in tablets and smart
phones), sound in enclosures of all sizes, such as school rooms,
offices, auditoriums and living rooms, and fluid-structure
interaction. Numerical examples and summary charts are given
throughout the text to make the material easily applicable to
practical design. New to this edition: A chapter on electrostatic
loudspeakers A chapter on vibrating surfaces (membranes, plates,
and shells) Readers will find this to be a valuable resource for
experimenters, acoustical consultants, and to those who anticipate
being engineering designers of audio equipment. It will serve as
both a text for students in engineering departments and as a
valuable reference for practicing engineers.
It was not until 1971 that the authority for defining scientific
units, the General Conference of Weights and Measures got around to
defining the unit that is the basis of chemistry (the mole, or the
quantity of something). Yet for all this tardiness in putting the
chemical sciences on a sound quantitative basis, chemistry is an
old and venerable subject and one naturally asks the question, why?
Well, the truth is that up until the mid-1920s, many physicists did
not believe in the reality of molecules. Indeed, it was not until
after the physics community had accepted Ernest Rutherford's 1913
solar-system-like model of the atom, and the quantum mechanical
model of the coupling of electron spins in atoms that physicists
started to take seriously the necessity of explaining the chemical
changes that chemists had been observing, investigating and
recording since the days of the alchemists.
Optical properties, particularly in the infrared range of
wavelengths, continue to be of enormous interest to both material
scientists and device engineers. The need for the development of
standards for data of optical properties in the infrared range of
wavelengths is very timely considering the on-going transition of
nano-technology from fundamental R&D to manufacturing.
Radiative properties play a critical role in the processing,
process control and manufacturing of semiconductor materials,
devices, circuits and systems. The design and implementation of
real-time process control methods in manufacturing requires the
knowledge of the radiative properties of materials. Sensors and
imagers operate on the basis of the radiative properties of
materials. This book reviews the optical properties of various
semiconductors in the infrared range of wavelengths. Theoretical
and experimental studies of the radiative properties of
semiconductors are presented. Previous studies, potential
applications and future developments are outlined. In Chapter 1, an
introduction to the radiative properties is presented. Examples of
instrumentation for measurements of the radiative properties is
described in Chapter 2. In Chapters 3-11, case studies of the
radiative properties of several semiconductors are elucidated. The
modeling and applications of these properties are explained in
Chapters 12 and 13, respectively. In Chapter 14, examples of the
global infrastructure for these measurements are illustrated.
