This is the first book in a four-part series 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.
The present Part 1 consists of four chapters. Chapter 1 begins with
a discussion of Continuum Hypothesis, which is followed by an
introduction to macroscopic functions, the velocity vector,
pressure, density, and enthalpy. We then analyse the forces acting
inside a fluid, and deduce the Navier-Stokes equations for
incompressible and compressible fluids in Cartesian and curvilinear
coordinates. In Chapter 2 we study the properties of a number of
flows that are presented by the so-called exact solutions of the
Navier-Stokes equations, including the Couette flow between two
parallel plates, Hagen-Poiseuille flow through a pipe, and Karman
flow above an infinite rotating disk. Chapter 3 is devoted to the
inviscid incompressible flow theory, with particular focus on
two-dimensional potential flows. These can be described in terms of
the "complex potential", allowing the full power of the theory of
functions of complex variables to be used. We discuss in detail the
method of conformal mapping, which is then used to study various
flows of interest, including the flows past Joukovskii aerofoils.
The final Chapter 4 is concerned with compressible flows of perfect
gas, including supersonic flows. Particular attention is given to
the theory of characteristics, which is used, for example, to
analyse the Prandtl-Meyer flow over a body surface bend and a
corner. Significant attention is also devoted to the shock waves.
The chapter concludes with analysis of unsteady flows, including
the theory of blast waves.
In the high energy gas flows, associating high velocities and high
temperatures, physical and chemical processes such as molecular
vibrational excitation, dissociation, ionisation or various
reactions take palce and deeply influence the structure of the
flows. The characteristic times of these processes have the same
order of magnitude as aerodynamic characteristic times so that
these reactive media are generally in thermodynamic and chemical
non-equilibrium. This book presents a general introductory study of
these media. In the first part their fundamental statistical
aspects are described, starting from their discrete structure and
taking into account the interactions between elementary particles:
the transport phenomena, relaxation and kinetics as well as their
coupling are thus analysed and illustrated by many examples. The
second part deals with the macroscopic re-entry bodies. Finally the
experimental aspects of these flows, their simulations in shock
tube and shock tunnel are described as well as their application,
particularly in the aero- spatial domain.
This book is intended for researchers and students that have
acquired basic knowledge in thermodynamics, statistical physics and
fluid mechanics. It must also interest the engineers engaged in
research and industry related to the applications of the reactive
flows, in particular in the aerospace field and, more generally,
all the researchers trying to simulate and calculate complex
reactive flows.
Munson, Young, and Okiishi's Fundamentals of Fluid Mechanics is
intended for undergraduate engineering students for use in a first
course on fluid mechanics. Building on the well-established
principles of fluid mechanics, the book offers improved and evolved
academic treatment of the subject. Each important concept or notion
is considered in terms of simple and easy-to-understand
circumstances before more complicated features are introduced. The
presentation of material allows for the gradual development of
student confidence in fluid mechanics problem solving. This
International Adaptation of the book comes with some new topics and
updates on concepts that clarify, enhance, and expand certain ideas
and concepts. The new examples and problems build upon the
understanding of engineering applications of fluid mechanics and
the edition has been completely updated to use SI units.
Microelectromechanical systems (MEMS) device applications are
common in many areas. Micromirror arrays are used as video
projectors; microsensors find their application for measuring
acceleration, temperature, and pressure; and they can also be used
in the medical field for measuring blood pressure. Microfluidics
have also been widely employed in life sciences applications, such
as drug development and administration, point-of-care devices, and
more. To use these technologies to their fullest extent, further
research is needed. Advances in MEMS and Microfluidic Systems
explores the emerging research and advances in MEMS devices and
microfluidic systems applications. It features in-depth chapters on
microfluidic device design and fabrication as well as on the
aspects of devices/systems, characterization, and comparative
research findings. Covering topics such as biosensors,
lab-on-a-chip, and microfluidic technology, this premier reference
source is an indispensable resource for engineers, health
professionals, students and educators of higher education,
librarians, researchers, and academicians.
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.
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.
The book is an introduction to the subject of fluid mechanics,
essential for students and researchers in many branches of science.
It illustrates its fundamental principles with a variety of
examples drawn mainly from astrophysics and geophysics as well as
from everyday experience. Prior familiarity with basic
thermodynamics and vector calculus is assumed.
