Computational Gasdynamics 1st Edition by Culbert B. Laney (PDF)

Description

Numerical methods are indispensable tools in the analysis of complex fluid flows. This book focuses on computational techniques for high-speed gas flows, especially gas flows containing shocks and other steep gradients. The book decomposes complicated numerical methods into simple modular parts, showing how each part fits and how each method relates to or differs from others. The text begins with a review of gasdynamics and computational techniques. Next come basic principles of computational gasdynamics. The last two parts cover basic techniques and advanced techniques. Senior and graduate level students, especially in aerospace engineering, as well as researchers and practising engineers, will find a wealth of invaluable information on high-speed gas flows in this text.

User’s Reviews

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐This is a good book but I feel it skimps on the foundation. Compared to other beginner books, as this was supposed to address, was not a beginners book.

⭐This book is excelente to study high resolution schemes. I suggest it for everybody. Good reading and good work with the suggested algorithms. Good service of the seller transport.

⭐This book is a detailed account of the Eulerian numerical methods used for the solution of hyperbolic pde’s such as the standard scalar conservation laws of fluid mechanics and gas dynamics. The book directly investigates gas dynamiocs rather than fluid dynamics although it has application there as well through the very successful Godunov method used for multiphase flow and compressible flow leading to shocks.There are several parts: Part I: a lead in to gas dynamics, waves and scalar conservation laws as well as the Riemann problem; followed by Part II: Computational review covering the simplest aspects of numerical methods such as numerical discretisation and error, interpolation, piecewise functions; Part III: Gas Dynamics itself involving the CFL concdition, upwinding methods, artificial viscosity, linear and non-linear stability; Part IV: Methods of Gas dynamics, for scalar conservation laws and the Euler equations; Part V: advanced methods leading into flux avergaing, flux limited methods, flux corrected methods, hybrid methods and solution averaging.The book deals mainly with numerical techniques for one dimension of space and time although there is a small chapter at the end for multidimensions. In this sense it is deficient, but it must be remembered that 1D methods must be mastered before considering the extension to 2 or 3 dimensions. This is a very detailed book leaving nothing out and explaining the techniques in great detail and in simple language without getting lost. Compare this with the far more difficult approach used by Leveque in his book: “Finite Difference Methods for Differential Equations”. If you wish to deeply understand the area then this is your text with over 600 pages making up the book its worth every cent although the rather high price of around US$60 is too high for most students. If you can afford it buy it, there is no better book for both an introduction and detail, most of the material is covered elsewhere in class notes and research papers but the fact it is explained in a single book with good continuity is a godsend.

⭐I have to admit that I was at first disappointed to see that the book was loaded with description of schemes in 1-D, with scant space dedicated to multi-dimensional problems. However, I must say that the coverage is easily the most clear and complete of the books on this subject. Other texts may be required to flesh out the schemes and boundary conditions in multi-dimensional space, but a reader will be well served with the good fundamental base that this text provides.

⭐Has a good style: * Gives clear decription of physics * Gives a good introduction to basic numerics * Clearly explains various techniques developed over the last few decades, and the incentive behind their development * Up to date, with many modern schemes

⭐i would like to thank the author for this marvelous book.The first 184 pages are a detailed revision of basic principles, which is something not found in the majority of CFD books.This books focus is on the finite difference and volume methods.This book is for researchers who work on compressible codes.good luck

⭐excellent book which gives a rich overview from basis up to specialized information on this difficult subjectIn addition the service was as good as expected
