内容説明
For junior/senior and graduate-level courses in Aerodynamics, Mechanical Engineering, and Aerospace Engineering Revised to reflect the technological advances and modern application in Aerodynamics, the Sixth Edition of Aerodynamics for Engineers merges fundamental fluid mechanics, experimental techniques, and computational fluid dynamics techniques to build a solid foundation for students in aerodynamic applications from low-speed through hypersonic flight. It presents a background discussion of each topic followed by a presentation of the theory, and then derives fundamental equations, applies them to simple computational techniques, and compares them to experimental data. Teaching and Learning Experience To provide a better teaching and learning experience, for both instructors and students, this program will: *Apply Theory and/or Research: An excellent overview of manufacturing conceptswith a balance of relevant fundamentals and real-world practices. *Engage Students: Examples and industrially relevant case studies demonstrate the importance of the subject, offer a real-world perspective, and keep students interested.
