Why this book?

This book offers an introductory course in theoretical and computation fluid dynamics, presented in a way that unifies theory, scientific computer programming, and numerical computation. Computational algorithms are developed immediately after problem formulations, and numerical methods are introduced alongside. The approach is truly introductory with a minimum of prerequisites. Intended audience includes undergraduate and entry-level graduate students, and a broad class of scientists and engineers with a general interest in scientific computing.

Software

This book is accompanied by the software library FDLIB whose directories explicitly illustrate how algorithms translate into code insructions. The codes of FDLIB range from introductory to advanced, and the problems considered span a wide range of applications. The programs are written in a modular fashion that allows modification and post-processing, including graphics and animation.

Excerpts from the preface

Ready access to computers on an institutional and personal level has defined a new era in learning and teaching. The opportunity to extend the subject matter of traditional scientific and engineering disciplines into the realm of scientific computing has become not only desirable, but also necessary as an effective tool of teaching and learning. Thanks to portability and low overhead and operating cost, experimentation by numerical simulation has become a viable substitute, and occasionally the only alternative, to physical experimentation.

The new approach has motivated the writing of texts and monographs from a new perspective that incorporates numerical and computer programming aspects as an integral part of the curicullum: methods, concepts, and ideas should be presented in a unified fashion that motivates and underlines the necessity of the new elements, but does not compromise the rigour of the classical approach and does not oversimplify.

Interfacing fundamental concepts and practical methods of scientific computing can be done on different levels distinguished by the texture of the weaving. In one approach, theory and implementation are kept complementary and presented in a sequential fashion. In a second approach, the coupling involves two intermediate steps: deriving computational methods and simulation algorithms immediately following problem formulations; and translating equations into computer code instructions. The author of this book appreciates the advantages of the second approach and advocates its usage as a means of enhanced learning: scientific programming offers a powerfull venue for developing analytical skills and physical insight.
