Recent advances in scientific computing have caused the field of
aerodynamics to change at a rapid pace, simplifying the design
cycle of aerospace vehicles enormously - this book takes the
readers from core concepts of aerodynamics to recent research,
using studies and real-life scenarios to explain problems and their
solutions. This book presents in detail the important concepts in
computational aerodynamics and aeroacoustics taking readers from
the fundamentals of fluid flow and aerodynamics to a more in-depth
analysis of acoustic waves, aeroacoustics, computational modelling
and processing. This book will be of use to students in multiple
branches of engineering, physics and applied mathematics.
Additionally, the book can also be used as a text in professional
development courses for industry engineers and as a self-help
reference for active researchers in both academia and the industry.
The role of high performance computing in current research on
transitional and turbulent flows is undoubtedly very important.
This review volume provides a good platform for leading experts and
researchers in various fields of fluid mechanics dealing with
transitional and turbulent flows to synergistically exchange ideas
and present the state of the art in the fields.Contributed by
eminent researchers, the book chapters feature keynote lectures,
panel discussions and the best invited contributed papers.
This book provides state-of-art information on high-accuracy
scientific computing and its future prospects, as applicable to the
broad areas of fluid mechanics and combustion, and across all speed
regimes. Beginning with the concepts of space-time discretization
and dispersion relation in numerical computing, the foundations are
laid for the efficient solution of the Navier-Stokes equations,
with special reference to prominent approaches such as LES, DES and
DNS. The basis of high-accuracy computing is rooted in the concept
of stability, dispersion and phase errors, which require the
comprehensive analysis of discrete computing by rigorously applying
error dynamics. In this context, high-order finite-difference and
finite-volume methods are presented. Naturally, the coverage also
includes fundamental notions of high-performance computing and
advanced concepts on parallel computing, including their
implementation in prospective hexascale computers. Moreover, the
book seeks to raise the bar beyond the pedagogical use of
high-accuracy computing by addressing more complex physical
scenarios, including turbulent combustion. Tools like proper
orthogonal decomposition (POD), proper generalized decomposition
(PGD), singular value decomposition (SVD), recursive POD, and
high-order SVD in multi-parameter spaces are presented. Special
attention is paid to bivariate and multivariate datasets in
connection with various canonical flow and heat transfer cases. The
book mainly addresses the needs of researchers and doctoral
students in mechanical engineering, aerospace engineering, and all
applied disciplines including applied mathematics, offering these
readers a unique resource.
Addressing classical material as well as new perspectives,
Instabilities of Flows and Transition to Turbulence presents a
concise, up-to-date treatment of theory and applications of viscous
flow instability. It covers materials from classical instability to
contemporary research areas including bluff body flow instability,
mixed convection flows, and application areas of aerospace and
other branches of engineering. Transforms and perturbation
techniques are used to link linear instability with receptivity of
flows, as developed by the author. The book: Provides complete
coverage of transition concepts, including receptivity and flow
instability Introduces linear receptivity using bi-lateral
Fourier-Laplace transform techniques Presents natural laminar flow
(NLF) airfoil analysis and design as a practical application of
classical and bypass transition Distinguishes strictly between
instability and receptivity, which leads to identification of wall-
and free stream-modes Describes energy-based receptivity theory for
the description of bypass transitions Instabilities of Flows and
Transition to Turbulence has evolved into an account of the
personal research interests of the author over the years. A
conscious effort has been made to keep the treatment at an
elementary level requiring rudimentary knowledge of calculus, the
Fourier-Laplace transform, and complex analysis. The book is
equally amenable to undergraduate students, as well as researchers
in the field.
This book highlights by careful documentation of developments what
led to tracking the growth of deterministic disturbances inside the
shear layer from receptivity to fully developed turbulent flow
stages. Associated theoretical and numerical developments are
addressed from basic level so that an uninitiated reader can also
follow the materials which lead to the solution of a long-standing
problem. Solving Navier-Stokes equation by direct numerical
simulation (DNS) from the first principle has been considered as
one of the most challenging problems of understanding what causes
transition to turbulence. Therefore, this book is a very useful
addition to advanced CFD and advanced fluid mechanics courses.
