State-of-the-art numerical methods for solving complex engineering problems Great strides in computer technology have been made in the years since the popular first edition of this book was published. Several excellent software packages now help engineers solve complex problems. Making the most of these programs requires a working knowledge of the numerical methods on which the programs are based. Numerical Methods for Engineering Application provides that knowledge. While it avoids intense mathematical detail, Numerical Methods for Engineering Application supplies more in-depth explanations of methods than found in the typical engineer's numerical "cookbook." It offers complete coverage of most commonly encountered algebraic, interpolation, and integration problems. Ordinary differential equations are examined in great detail, as are three common types of partial differential equations--parabolic, elliptic, and hyperbolic. The author also explores a wide range of methods for solving initial and boundary value problems. This complete guide to numerical methods for solving engineering problems on computers provides:* Practical advice on how to select the best method for a given problem* Valuable insights into how each method works and why it is the best choice* Complete algorithms and source code for all programs covered* Code from the book and problem-solving programs designed by the author available from the author's website Numerical Methods for Engineering Application is a valuable working resource for engineers and applied physicists. It also serves as an excellent upper-level text for physics and engineering students in courses on modern numerical methods.

The Theory of Neutron Slowing Down in Nuclear Reactors focuses on one facet of nuclear reactor design: the slowing down (or moderation) of neutrons from the high energies with which they are born in fission to the energies at which they are ultimately absorbed. In conjunction with the study of neutron moderation, calculations of reactor criticality are presented. A mathematical description of the slowing-down process is given, with particular emphasis on the problems encountered in the design of thermal reactors. This volume is comprised of four chapters and begins by considering the problems of neutron moderation and their importance in all types of reactors. An asymptotic reactor model is described, and the calculation of the elastic scattering frequency is explained. Subsequent chapters focus on the process of slowing down in finite and infinite medium by analyzing capture by individual resonances; resonance integrals in heterogeneous systems; the slowing-down kernels; the spherical harmonics method; statistical methods; and small source theory. The final chapter presents numerical solutions of the Boltzmann equation and covers topics such as the multigroup approach, group constants, and solution of the multigroup equations. This book will be a useful resource for nuclear physicists and engineers.

This book is a guide to numerical methods for solving fluid dynamics problems. The most widely used discretization and solution methods, which are also found in most commercial CFD-programs, are described in detail. Some advanced topics, like moving grids, simulation of turbulence, computation of free-surface flows, multigrid methods and parallel computing, are also covered. Since CFD is a very broad field, we provide fundamental methods and ideas, with some illustrative examples, upon which more advanced techniques are built. Numerical accuracy and estimation of errors are important aspects and are discussed in many examples. Computer codes that include many of the methods described in the book can be obtained online. This 4th edition includes major revision of all chapters; some new methods are described and references to more recent publications with new approaches are included. Former Chapter 7 on solution of the Navier-Stokes equations has been split intotwo Chapters to allow for a more detailed description of several variants of the Fractional Step Method and a comparison with SIMPLE-like approaches. In Chapters 7 to 13, most examples have been replaced or recomputed, and hints regarding practical applications are made. Several new sections have been added, to cover, e.g., immersed-boundary methods, overset grids methods, fluid-structure interaction and conjugate heat transfer.

Computational fluid dynamics, commonly known under the acronym ''CFD'', is undergoing significant expansion in terms of both the number of courses offered at universities and the number of researchers active in the field. There are a number of software packages available that solve fluid flow problems; the market is not quite as large as the one for structural mechanics codes, in which the use of finite element methods is well established. The lag can be explained by the fact that CFD problems are, in general, more difficult to solve. However, CFD codes are slowly being accepted as design tools by industrial users. At present, users of CFD need to be fairly knowledgeable and this requires education of both students and working engineers. The present book is an attempt to fill this need. It is our belief that, to work in CFD, one needs a solid background in fluid mechanics and numerical analysis; significant errors have been made by peo ple lacking knowledge in one or the other. We therefore encourage the reader to obtain a working knowledge of these subjects before entering into a study of the material in this book. Because different people view numerical meth ods differently, and to make this work more self-contained, we have included two chapters on basic numerical methods in this book. The book is based on material offered by the authors in courses at Stanford University, the Uni versity of Erlangen-Niirnberg and the University of Hamburg.

This book provides a unique assembly of state-of-the-art articles concerned with a wide range of fundamental and applied issues, including turbulence parameterization, numerical uncertainty, complex turbulence, flow-structure interactions, atmosphere-ocean turbulence and turmachinery flows. The articles provide specific examples of the most recent applications of direct and large eddies methods. These methods have been very successful in providing new insight into the structure of turbulent flows and are becoming feasable in real engineering and environmental problems with complex geometries. This volume will be a very valuable source book for researchers and graduate students embarking on studies in turbulent flow simulation.

Dieses Buch behandelt numerische Methoden zur Lösung fluiddynamischer Probleme. Die gängigsten Diskretisierungs- und Lösungsmethoden, die auch in den meisten kommerziellen Programmen zu finden sind, werden ausführlich beschrieben. Einige fortgeschrittene Themen, wie bewegliche Gitter, Simulation von Turbulenz, Berechnung von Strömungen mit freien Oberflächen, Mehrgitterverfahren und paralleles Rechnen, werden ebenfalls behandelt. Da dies ein sehr weites Feld ist, werden nur die grundlegenden Methoden und Ideen, auf denen fortgeschrittene Techniken aufgebaut sind, ausführlich beschrieben. Die Theorie wird durch einige anschauliche Beispiele untermauert. Numerische Genauigkeit und Fehlerabschätzung sind wichtige Aspekte und werden in vielen Beispielen diskutiert. Rechenprogramme, die viele der im Buch beschriebenen Methoden enthalten, können von der Homepage www.cfd-peric.de. bezogen werden. Die 2. Auflage enthält eine umfassende Überarbeitung aller Kapitel; einige neue Methoden werden beschrieben und Verweise auf neuere Publikationen mit neuen Ansätzen sind enthalten. Das ehemalige Kapitel 7 über die Lösung der Navier-Stokes-Gleichungen wurde in zwei Kapitel aufgeteilt, um eine detailliertere Beschreibung mehrerer Varianten der Fractional-Step-Methode und einen Vergleich mit SIMPLE-artigen Ansätzen zu ermöglichen. In den Kapiteln 7 bis 13 wurden die meisten Beispiele ersetzt oder neu berechnet, mit Hinweisen auf praktische Anwendungen. Mehrere neue Abschnitte wurden hinzugefügt, um z.B. die Behandlung von überlappenden Gittern, Fluid-Struktur-Wechselwirkung und Wärmeübertragung abzudecken.Dieses Buch richtet sich an Studierende, die einen Kurs über Berechnungsmethoden in der Strömungsmechanik besuchen, und Anwender kommerzieller CFD-Software, für die es nützlich ist, weil es die in Softwarehandbüchern enthaltenen Informationen ergänzt.
