Preface

Aerodynamics is a branch of physics concerned with the motion of air and the resulting forces acting on solid objects. In other words, aerodynamics is primarily related to the forces of drag and lift, and moments on airfoils, wings, fuselages, engine nacelles, and most importantly, whole airplane configurations, which are caused by air passing over and around solid bodies. It is also concerned with the design of automobiles, high-speed trains, and ships, as well as with the construction of such structures as bridges and tall buildings to determine their resistance to high winds. The basic principles are relatively easy to understand; they include how fluids flow in different ways. Most of the equations from fluid dynamics apply to aerodynamics as well, including all the governing equations, turbulence, boundary layer theory, and ideal gas assumption. This book presents novel ideas that traverse traditional disciplinary boundaries as well as introduces a wide spectrum of viewpoints and approaches in applied aerodynamics of the third millennium. The book will be of interest to those working in the fields of propulsion systems, power generation systems, the flight of aircraft, fluid flow, combustion, and other phenomena.
