Large-Eddy Simulations of Turbulence
This slim volume is an introduction for
those new to large-eddy simulation, direct numerical simulation, and Reynolds-averaged
Navier-Stokes simulation, but is also a useful research resource. Of particular
interest in the text is a detailed discussion in Chapter 2 of vorticity,
pressure, and the velocity gradient tensor, quantities useful for probing
the results of a simulation, particularly when looking for coherent vortices
and coherent structures. Chapters 4 and 5 feature an in-depth discussion
of spectral subgrid-scale modeling. Although physical-space models are
generally more readily applied, spectral models give insight into the
requirements and limitations in subgrid-scale modeling and backscattering.
Fundamental of Applied Dynamics
Whether analyzing the stability of an underwater
robot or predicting the trajectory of a satellite, today's engineers
are solving increasingly difficult and unconventional problems in dynamics.
This book claims to provide the essential knowledge to help students solve
problems in classical mechanics. In each chapter, general concepts are
presented first, followed by illustrated examples and worked-out problems.
Precise notation and consistent methodology are used where possible, so
that the student will recognize principles common to particle dynamics,
system dynamics, and rigid body dynamics. The book covers Newtonian mechanics,
without Hamiltonian or Lagrangian formalism.
This second edition of Fundamentals of Space Systems has undertaken to enhance the contents of the first edition in two chief ways. First, the material has been updated to reflect changes in the technology and science of spacecraft systems engineering that have occurred since the publication of the initial edition. Second, an attempt has been made to make the material more suitable for a space systems course as a prerequisite to a senior class project to design and perhaps build and launch a spacecraft or spacecraft instrument. In addition, more problems have been provided and a chapter pulling together the design concepts for a simplified spacecraft has been added. The book seeks to expose the reader to the fundamentals of each of the subsystems in a spacecraft to a depth that should permit the reader to carry out a conceptual design. This volume is part of the Johns Hopkins University Applied Physics Laboratory Series in Science and Engineering.
This new WIT Press offering contains papers presented at the Third International Conference on Comparing Design in Nature With Science and Engineering. It was held in The New Forest, U.K., in May of this year. The 32 peer-reviewed papers in the book cover: shape and form in engineering and nature; nature and architectural design; biomimetics; natural materials engineering; bioengineering; solutions from nature; sustainability studies, and education and training. This is Volume 87 in WIT Press's Transactions on Ecology and the Environment.
An Introduction to Numerical Methods:
A Matlab Approach. Second Edition.
A range of useful algorithms is introduced
to readers in the second edition of this book. Incorporating the use of
Matlab as a key part of the text, the book has new information on numerical
optimization and the finite element method. It includes real-world examples
in each section as well as additional exercises, applied problems, and
computer problems. The authors cover topics such as direct and iterative
methods, interpolation, spline functions, the concepts of least squares,
numerical differentiation, and integration. A CD-ROM accompanies the text,
supplying many simple Matlab functions.
An Introduction to Partial Differential
Equations. Second Edition.
Partial differential equations are fundamental
to the modeling of natural phenomena, arising in every field of science.
Thus, the desire to understand the solutions of these equations has always
had a prominent place in the efforts of mathematicians; it has inspired
such diverse fields as complex function theory, functional analysis, and
algebraic topology. This book aims to provide the background necessary
to initiate work on a Ph.D. thesis in partial differential equations.
This edition features new problems throughout, and they have been rearranged
in each section from the simplest to the most difficult. New examples
have also been added, and material on Sobolev spaces has been rearranged
and expanded.
Hydrodynamic Fluctuations in Fluids and
Fluid Mixtures
In this book, the authors deal with density,
temperature, velocity, and concentration fluctuations in fluids and fluid
mixtures. The book first reviews thermal fluctuations in equilibrium fluids
on the basis of fluctuating hydrodynamics. It then shows how the method
of fluctuating hydrodynamics can be extended to deal with hydrodynamic
fluctuations in fluids that are not in thermodynamic equilibrium. While
fluctuations in equilibrium fluids are generally short ranged unless the
system is close to a critical point, fluctuations in nonequilibrium fluids
are always spatially long ranged. The book claims to provide the first
comprehensive treatment of fluctuations in fluids and fluid mixtures brought
out of equilibrium by a temperature or concentration gradient, but that
are still in a quiescent state without any convection or turbulence.
Structural Shear Joints: Analyses, Properties
and Design for Repeated Loading
This book describes the mechanical response
of butt, lap, and doubler joints. The findings apply to shear connections
in civil, aerospace, and other mechanical structures subjected to repeated
loading. The findings are intended for engineers and NDE practitioners
concerned with the design of new, as well as inspection and maintenance
of existing shear joints. Fatigue strengths of the joints are derived
using conventional, material S-N data, and the joint stress concentration
factor. The authors treat the different modes of load transmission: the
bearing, clamped, and adhesive modes, and joint geometry; fastener spacing
and numbers of fastener rows, and fastener geometry; standard and countersunk
heads, and self-piercing and interference fasteners. The book contains
analyses that relate global features to the local conditions that govern
fatigue damage, such as the contact pressures, interface slips, and the
intensity and locations of stress concentrations. The book also addresses
riveted and bolted joints, aluminum connections for airframes and automotive
bodies, and steel connections for machines and bridges.
