Titelbeschreibung

New edition of the popular textbook, comprehensively updated throughout and now includes a new dedicated website for gas dynamic calculations The thoroughly revised and updated third edition of Fundamentals of Gas Dynamics maintains the focus on gas flows below hypersonic. This targeted approach provides a cohesive and rigorous examination of most practical engineering problems in this gas dynamics flow regime. The conventional one-dimensional flow approach together with the role of temperature-entropy diagrams are highlighted throughout. The authors—noted experts in the field—include a modern computational aid, illustrative charts and tables, and myriad examples of varying degrees of difficulty to aid in the understanding of the material presented. The updated edition of Fundamentals of Gas Dynamics includes new sections on the shock tube, the aerospike nozzle, and the gas dynamic laser. The book contains all equations, tables, and charts necessary to work the problems and exercises in each chapter. This book’s accessible but rigorous style: <ul> <li>Offers a comprehensively updated edition that includes new problems and examples</li> <li>Covers fundamentals of gas flows targeting those below hypersonic</li> <li>Presents the one-dimensional flow approach and highlights the role of temperature-entropy diagrams</li> <li>Contains new sections that examine the shock tube, the aerospike nozzle, the gas dynamic laser, and an expanded coverage of rocket propulsion</li> <li>Explores applications of gas dynamics to aircraft and rocket engines</li> <li>Includes behavioral objectives, summaries, and check tests to aid with learning</li> </ul> Written for students in mechanical and aerospace engineering and professionals and researchers in the field, the third edition of Fundamentals of Gas Dynamics has been updated to include recent developments in the field and retains all its learning aids.
