This computational aerodynamics (CA) textbook is written at the undergraduate level, based on years of teaching focused on developing the engineering skills required to become an intelligent user of aerodynamic codes, unlike most available books which focus on learning how to write codes. This is done by taking advantage of CA codes that are now freely available and doing projects to learn the basic numerical and aerodynamic concepts require. The authors believe that new and vibrant ways to interact with CA are important in order to improve understanding of aerodynamics. This book includes a number of unique features to make studying Computational Aerodynamics more enjoyable. These include: The computer programs used in the book's projects are all open source and accessible to students and practicing engineers alike on the book web site, www.cambridge.org/cummings CA Concept Boxes appear throughout the book to make material more relevant and to provide interesting asides from the material at hand Flow Visualization Boxes are used throughout the book to give readers the opportunity to see fluid dynamic flows first hand Profiles of both experienced and beginning practitioners of CA are included throughout to give a more personal dimension to the practice of numerical simulations of aerodynamics Best Practices summaries are included at the end of most chapters to provide real world guidelines for how CA is typically used The website includes access to images, movies, programs, CA codes, additional material, and links to a variety of resources vital to the discussions contained within the book (www.cambridge.org/cummings)"
