Aerodynamics

Aerodynamics is the study of physics that examines the presence and effects of air or gases, especially when interacting with moving objects or living organisms. Aerodynamics are the forces that act on the surface of a body in motion moving through the air, or the pressure exerted by air flowing past a stationary object. Examples of airflow around bodies are: gas in engines and furnaces, air conditioning of buildings, vehicles, buildings and bridges, bird and insect flight, musical instruments, etc.

Air is viscous; viscosity is the ability of a flowing liquid or gas to resist the flow of objects going through it. In air, viscous forces are generally small in comparison with other inertia forces, which can cause instability and turbulence when objects move through the...
