Practical applications and examples highlight this treatment of
computational modeling for handling complex flowfields. The author
draws upon personal research to address both macroscopic and
microscopic features. A reference for researchers and graduate
students of many backgrounds, it also functions as a text for
learning essential computation elements. 1994 edition.
This advanced-level text describes several computational techniques
that can be applied to a variety of problems in thermo-fluid
physics, multi-phase flow, and applied mechanics involving moving
flow boundaries. Step-by-step discussions of numerical procedures
include examples that employ algorithms to solve problems. 1990
edition.
Insect-scale flapping wing flight vehicles can conduct
environmental monitoring, disaster assessment, mapping, positioning
and security in complex and challenging surroundings. To develop
bio-inspired flight vehicles, systematic probing based on the
particular category of flight vehicles is needed. This Element
addresses the aerodynamics, aeroelasticity, geometry, stability and
dynamics of flexible flapping wings in the insect flight regime.
The authors highlight distinct features and issues, contrast
aerodynamic stability between rigid and flexible wings, present the
implications of the wing-aspect ratio, and use canonical models and
dragonflies to elucidate scientific insight as well as technical
capabilities of bio-inspired design.
This is an ideal book for graduate students and researchers
interested in the aerodynamics, structural dynamics and flight
dynamics of small birds, bats and insects, as well as of micro air
vehicles (MAVs), which present some of the richest problems
intersecting science and engineering. The agility and spectacular
flight performance of natural flyers, thanks to their flexible,
deformable wing structures, as well as to outstanding wing, tail
and body coordination, is particularly significant. To design and
build MAVs with performance comparable to natural flyers, it is
essential that natural flyers' combined flexible structural
dynamics and aerodynamics are adequately understood. The primary
focus of this book is to address the recent developments in
flapping wing aerodynamics. This book extends the work presented in
Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).
Low Reynolds number aerodynamics is important to a number of
natural and man-made flyers. Birds, bats, and insects have been of
interest to biologists for years, and active study in the aerospace
engineering community, motivated by interest in micro air vehicles
(MAVs), has been increasing rapidly. The primary focus of this book
is the aerodynamics associated with fixed and flapping wings. The
book consider both biological flyers and MAVs, including a summary
of the scaling laws-which relate the aerodynamics and flight
characteristics to a flyer's sizing on the basis of simple
geometric and dynamics analyses, structural flexibility,
laminar-turbulent transition, airfoil shapes, and unsteady flapping
wing aerodynamics. The interplay between flapping kinematics and
key dimensionless parameters such as the Reynolds number, Strouhal
number, and reduced frequency is highlighted. The various unsteady
lift enhancement mechanisms are also addressed, including
leading-edge vortex, rapid pitch-up and rotational circulation,
wake capture, and clap-and-fling.
Many of the significant issues in fluid dynamics occur at
interfaces, that is, at the boundaries between differing fluids or
between fluids and solids. These issues are important in areas
ranging from aircraft flight, to the flow of blood in the heart, to
chemical vapour deposition. The subject is an area of active
research and development, owing to improved analytical,
experimental, and computational techniques. This book describes
research and applications in interfacial fluid dynamics and
stability. It is organized around five topics: Benard and
thermocapillary instabilities, shear and pressure induced
instabilities, waves and dispersions, multiphase systems, and
complex flows. Chapters have been contributed by internationally
recognized experts, both theoreticians and experimentalists.
Because of the range and importance of topics discussed, this book
will interest a broad audience of graduate students and researchers
in mechanical, aerospace, materials, and chemical engineering, as
well as in applied mathematics and physics.

Complex fluid flows are encountered widely in nature, in living
beings and in engineering practice. These flows often involve both
geometric and dynamic complexity and present problems that are
difficult to analyse because of their wide range of length and time
scales, as well as their geometric configuration. This book
describes some computational techniques and modelling strategies
for analysing and predicting complex transport phenomena. It
summarizes advances in the context of a pressure-based algorithm.
Among methods discussed are discretization schemes for treating
convection and pressure, parallel computing, multigrid methods, and
composite, multiblock techniques. With respect to physical
modelling, the book addresses issues of turbulence closure and
multiscale, multiphase transport from an engineering viewpoint.
Both fundamental and practical issues are considered, along with
the relative merits of competing approaches. Numerous examples are
given throughout the text. Mechanical, aerospace, chemical and
materials engineers can use the techniques presented in this book
to tackle important, practical problems more effectively.
