An expert and contemporary presentation of computational analysis and design tools for professionals studying or applying the principles of aerodynamics
In Aerodynamics: A Computational Introduction, a distinguished aerospace engineer and researcher Krzysztof Fidkowski delivers an up-to-date and authoritative reference text covering the essentials of aerodynamics. The book covers key topics, including basic fluid dynamics, potential flow, airfoil theory, boundary layers, wing theory, and compressible flow.
Fidkowski takes a computation-first approach to the subject matter, presenting aerodynamics in a way that is compatible with the way the subject is handled in contemporary businesses and research labs. Aerodynamics offers numerical demonstrations, codes, and theory comparisons that make important derivations and conclusions easier to understand and apply.
Readers will also find:
- A self-contained introduction to the thermodynamics, mathematics, and numerical methods central to the subject of aerodynamics
- Comprehensive explorations of kinematics, dynamics, and potential flow
- Practical discussions of panel methods and airfoil theory, including design tools
- Numerical and analytical tools for boundary-layer analysis
- Complete treatment of finite-wing theory, including horseshoe vortices, lifting-line theory, and the vortex-lattice method.
Perfect for engineering students who want to learn how to apply basic numerical methods to large-scale aerodynamics problems, Aerodynamics: A Computational Introduction will also benefit professionals who wish to better understand aerodynamics and computational fluid dynamics.
