A wind tunnel is a room or passage through which air can be made to flow at controlled speeds. Wind tunnels are used to test new equipment or machinery, especially cars and aeroplanes. A chamber through which air is forced at controlled velocities in order to study the effects of aerodynamic flow around airfoils, scale models, or other objects. a large enclosed passage where engineers test aircraft etc by forcing air past them. Device for producing a controlled stream of air to study the effects on objects such as aircraft moving through air or the effects of moving air on models of stationary objects such as buildings. Applications of wind-tunnel research range from testing of airframes (the structures of aircraft and spacecraft) to research on the boundary layer, turbulence, drag, and lift. Measurements of air pressure and other characteristics at many points on the model yield information about how the total wind load is distributed. In addition to testing the effects of wind on aircraft and spacecraft, studies in wind tunnels have been used to solve design problems in automobiles, boats, trains, bridges, and buildings.
