Fundamentals of Wind Tunnel
The air, though unseen, is a very powerful force. The way it flows and the strength with which it flows affect us tremendously. The shape of the wings of an aircraft allows the airflow on top of the wing to flow faster and that helps the plane to fly. Strong winds on the upper floors of a high-rise building can cause great damage if the building is not properly designed. But how were the wings of a plane designed in such a way? How are buildings designed to withstand the destructive force of wind during a powerful storm? The information required to make them possible has come about through proper measurements and wind testing . The Wind Tunnel In very simple terms, a wind tunnel is a rather long tube enclosed in metal, glass, or even an entire building. The tunnel is equipped with powerful fans at both ends: one to blow air into the tunnel and the other to push air out of the tunnel. Wind tunnel testing facilities make it possible for scale models of buildings, ...
