Numerical Methods for Fluid Dynamics

Autor Dale R Durran
en Limba Engleză Hardback – 23 sep 2010

Apreciem, în primul rând, caracterul interdisciplinar al acestei lucrări publicate de Springer, care reușește să creeze o punte solidă între analiza numerică riguroasă și aplicațiile practice din meteorologie, oceanografie și fizica fluidelor. Numerical Methods for Fluid Dynamics nu se limitează la prezentarea abstractă a algoritmilor, ci îi ancorează direct în dinamica sistemelor geofizice, oferind cercetătorilor instrumentele necesare pentru modelarea fluxurilor complexe din atmosferă și hidrosferă. În această a doua ediție, autorul Dale R Durran rafinează prezentarea metodelor de modelare a ecuațiilor cu derivate parțiale, menținând un echilibru remarcabil între rigoarea matematică și aplicabilitatea inginerească. Subliniem progresia logică a volumului, care ghidează cititorul de la fundamentele ecuațiilor diferențiale ordinare și aproximările de transport unidimensional către tehnici avansate precum metodele spectrale, elementele finite și schemele de volum finit pentru legile de conservare. Notăm cu interes includerea unor capitole dedicate fenomenelor fizice specifice, cum sunt undele rapide nesemnificative și condițiile la limită non-reflectante, aspecte esențiale pentru stabilitatea modelelor numerice moderne. Această abordare extinde cadrul propus de Numerical Methods for Atmospheric and Oceanic Sciences de A. Chandrasekar cu date noi din domeniul schemelor TVC și al metodelor de flux corectat, oferind o profunzime matematică superioară manualelor introductive. Prin utilizarea unui set extins de probleme de test, Dale R Durran demonstrează proprietățile teoretice ale metodelor discutate, facilitând tranziția de la teorie la implementarea codului. Este o resursă care depășește simpla descriere a algoritmilor, oferind o perspectivă critică asupra limitărilor și avantajelor fiecărei tehnici în contextul dinamicii fluidelor computaționale.

De ce să citești această carte

Recomandăm această lucrare cercetătorilor și studenților la nivel de masterat sau doctorat care au nevoie de o bază matematică solidă pentru modelarea atmosferică și oceanică. Cititorul câștigă o înțelegere profundă a stabilității și preciziei schemelor numerice, primind un instrumentar complet — de la diferențe finite la metode semi-Lagrangiene — necesar pentru a dezvolta sau evalua modele climatice și de prognoză.

Recenzii

From the reviews of the second edition:
“This is a largely self-contained and relatively far-reaching presentation of numerical fluid dynamics. It is aimed towards practitioners (meteorologists, physicists, engineers), providing … a presentation of more mathematical depth than is frequently encountered in such books.” (H. Muthsam, Monatshefte für Mathematik, Vol. 166 (1), April, 2012)
“Durran’s direct and yet information-rich style makes this an excellent reference book. … This is a good book for postdocs and professors as well as students. … For an atmospheric modeler, this is probably the first book to buy. … book is a more direct path to algorithms for graduate students and researchers who already have some familiarity with atmospheric dynamics. … is worth a look by computational fluid dynamicists in other fields, especially those looking for ideas and insights outside their own particular specialties.” (SIAM Review, Vol. 54 (4), 2012)
“This book is an introduction to numerical methods for fluid dynamics. … The text could be useful to graduate students and scientists working in various branches of applied mathematics and engineering, not only in geophysical fluids. The material is intelligible to readers with a general mathematical background. The book includes exercises and is well illustrated with figures linking theoretical analyses to actual computations.” (Titus Petrila, Zentralblatt MATH, Vol. 1214, 2011)
From the reviews:
"...an excellent reference...should be brought to the attention of readers in meteorology, oceanography, physics, mechanics and engineering... an excellent text book...the extensiveness, theoretical and practical extent this book reaches make it a classical work." Acta Meteorologica Sinica
"...The book's unquestionable advantage is the clarity and simplicity in presenting virtually all basic ideas and methods of numerical analysis currentlyactively used in geophysical fluid dynamics." Physics of Atmosphere and Ocean

Textul de pe ultima copertă

This book is a major revision of Numerical Methods for Wave Equations in Geophysical Fluid Dynamics; the new title of the second edition conveys its broader scope. The second edition is designed to serve graduate students and researchers studying geophysical fluids, while also providing a non-discipline-specific introduction to numerical methods for the solution of time-dependent differential equations. The methods considered are those at the foundation of real-world atmospheric or ocean models, with the focus being on the essential mathematical properties of each method. The fundamental character of each scheme is examined in prototypical fluid-dynamical problems like tracer transport, chemically reacting flow, shallow-water waves, and waves in an internally stratified fluid. The book includes exercises and is well illustrated with figures linking theoretical analyses to results from actual computations. Changes from the first edition include new chapters, discussions and updates throughout.Dale Durran is Professor and Chair of Atmospheric Sciences and Adjunct Professor of Applied Mathematics at the University of Washington.Reviews from the First Edition:“This book will no doubt become a standard within the atmospheric science community, but its comfortable applied mathematical style will also appeal to many interested in computing advective flows and waves. It is a contemporary and worthy addition to the still-sparse list of quality graduate-level references on the numerical solution of PDEs." SIAM Review, 2000, 42, 755-756 (by David Muraki)“This book presents an extensive overview of past and current numerical methods used in the context of solving wave systems … It is directed primarily at flows that do not develop shocks and focuses on standard fluid problems including tracer transport, the shallow-water equations and the Euler equations … the book is well organized and written and fills a long-standing void for collected material on numericalmethods useful for studying geophysical flows." Bulletin of the American Meteorological Society, 2000, 81, 1080-1081 (by Robert Wilhelmson)

Caracteristici

Descriere

This scholarly text provides an introduction to the numerical methods used to model partial differential equations, with focus on atmospheric and oceanic flows. The book covers both the essentials of building a numerical model and the more sophisticated techniques that are now available. Finite difference methods, spectral methods, finite element method, flux-corrected methods and TVC schemes are all discussed. Throughout, the author keeps to a middle ground between the theorem-proof formalism of a mathematical text and the highly empirical approach found in some engineering publications. The book establishes a concrete link between theory and practice using an extensive range of test problems to illustrate the theoretically derived properties of various methods. From the reviews: "...the books unquestionable advantage is the clarity and simplicity in presenting virtually all basic ideas and methods of numerical analysis currently actively used in geophysical fluid dynamics." Physics of Atmosphere and Ocean
