valerie taylor on 23 Jul 13"A wind tunnel is used to study the influence of wind on moving bodies. The structure creates a near similar wind conditions as prevalent in nature when bodies move at high velocity. For this purpose, scaled down models of automobiles or aircrafts are kept inside the tunnel and high velocity airstreams are created and forces acting on the model are analyzed using suitable force measuring devices. Such measurements help in refining the body design"
