Numerical Computation of Internal and External Flows: The Fundamentals of Computational Fluid Dynamics [PDF ebook] 

The second edition of this book is a self-contained introduction to computational fluid dynamics (CFD). It covers the fundamentals of the subject and is ideal as a text or a comprehensive reference to CFD theory and practice. – New approach takes readers seamlessly from first principles to more advanced and applied topics. – Presents the essential components of a simulation system at a level suitable for those coming into contact with CFD for the first time, and is ideal for those who need a comprehensive refresher on the fundamentals of CFD. – Enhanced pedagogy features chapter objectives, hands-on practice examples and end of chapter exercises. – Extended coverage of finite difference, finite volume and finite element methods. – New chapters include an introduction to grid properties and the use of grids in practice. – Includes material on 2-D inviscid, potential and Euler flows, 2-D viscous flows and Navier-Stokes flows to enable the reader to develop basic CFD simulations. – Includes best practice guidelines for applying existing commercial or shareware CFD tools.
