Numerical Computation of Internal and External Flows by Charles Hirsch pdf free download. This book, which is published in two volumes, aims at introducing the reader to the essential steps involved in the numerical simulation of fluid flows by providing a guide from the initial step of the selection of a mathematical model to practical methods for their numerical discretization and resolution. The first volume, divided into four parts, is devoted to the fundamentals of numerical discretization techniques and attempts a systematic presentation of the successive steps involved in the definition and development of a numerical simulation.

The second, on the other hand, presents the applications of numerical methods and algorithms to selected flow models, from the full potential flow model to the systems of Euler and Navier-Stokes equations. Part I, covering Chapters 1 to 3, introduces the mathematical models corresponding to various levels of approximation of a flow system. We hope hereby to draw, if necessary, the reader’s attention to the range of validity and limitations of the different available flow models so that the user will be in a position to make a choicc in full awareness of its implications.

Part II is devoted to a presentation of the essentials of the most frequently applied discretization methods for differential equations, the finite difference (Chapter 4), finite element (Chapter 5) and finite volume methods (Chapter 6). Part III introduces the next step in the development of an algorithm, namely the methods for the analysis of the stability, convergence and accuracy properties of a selected discretization.

This is covered in Chapters 7 and 10, dealing, respectively, with basic definitions, the Von Neumann method, the method of the equivalent differential equation and the matrix method. Finally, Part IV covers the resolution methods for discretized equations. More particularly, integration methods which can be applied to systems of ordinary differential equations (in time) are discussed in Chapter 11 and iterative methods for the resolution of algebraic systems are discussed in Chapter 12
