Frequently Asked Question

What is Aerodynamics ?
The science that deals with motions of air and other gaseous fluids, and the forces acting on bodies when the bodies move through such fluids, or when fluids move against or around the bodies.
Hydrodynamics and aerodynamics are both branches of fluid dynamics, which is the study of fluids in motion. The fundamental laws governing the movements of gases, such as air, and liquids, such as water, are identical. Although many liquids are almost incompressible. The equations representing these natural laws are, however, so complex that although formulated over a hundred years ago, they cannot be easily solved to account for all situations and conditions. The equations which describe in a general fashion the motion of fluids were developed in 1820 and subsequently perfected by G.G. Stokes. At the beginning of the twentieth century, aerodynamics was introduced with the possibility of flight in air. It started with the same assumption as hydrodynamics with the added assumption of incompressibility replacing what was a fact for water

What is aeroelasticity ?
Aeroelasticity is distortion (as from bending or flexing) in a structure (as an airplane wing or a building) caused by aerodynamic forces.

When do I need to do Wind Tunnel Testing for Civil/Structural projects ?
Well, the answer is not that simple, so I suggest you read an article called "Wind Tunnel Testing a Breeze Through" by Scott Gamble, P.Eng or a copy of the article here.
