From Building Aerodynamics


Experimentation in aerodynamics started with Wind Tunnels, and still the majority of the experimental work is carried out in them. The new contender is Computer Fluid Dynamics (CFD): this science is developing and has its own advocates: the author is not one of these. Consequently any reader wishing to learn about CFD and its application to Building Aerodynamics will have to consult a book on that subject, he will find no help in these pages.

Building Aerodynamics is a very experimental subject, and has grown out of Aircraft Aerodynamics. The description of the wind is very complex, compared to the still air through which aircraft fly for most of their life. The wind has shear and turbulence which can only be described in statistical terms, and can approach from any direction. The shapes used are bluff shapes which cause the air to separate as it flows around them, rather than smooth sleek shapes, like wings and fuselages, to which the flow is attached.

Even with agreeable conditions, the aircraft aerodynamist had to resort to experimental measurements to quantify the parameters which theory showed were important

The aircraft engineers developed wind tunnel techniques which solved their problems satisfactorily, and, by the middle of the twentieth century, the body of techniques and experience was impressive.

By the middle of the twentieth century buildings, other than cathedral and similar buildings, were beginning to increase in size and reduce in weight so that wind loads began to form an important part of the...

Products & Services
Wind Tunnel Testing Services
Wind tunnel testing services provide test facilities and technical staff for aerodynamic testing. Tests may be performed on prototype aircraft, helicopters, trains, cars, or buildings; or for research and development (R&D) purposes.
Blades (wind turbine)
Wind turbine blades are air-foil shaped blades that harness wind energy and drive the rotor of a wind turbine.
Wind Turbines
Wind turbines convert the kinetic energy from wind into mechanical energy. When used with an electrical generator, the rotation of the wind turbine’s blades turns a shaft to produce electricity.
Exterior Doors
Exterior doors are designed and constructed for outdoor use. They allow personnel and equipment to enter and exit from buildings.
Filament Winding Machines
Filament winding machines place or wind continuous fibers on a mandrel surface in a precise geometric pattern. They are central components in fabric and composite material manufacturing.
