A wind tunnel is a research tool developed to assist with studying the effects of air moving over or around solid objects. The speed and flow of air in a wind tunnel can be measured in any of several ways. For instance, threads can be attached to the surface of study objects to detect flow direction and relative speed of air flow. Alternatively, dye or smoke can be injected upstream into the air stream and the streamlines followed by the dye particles can be photographed as the experiment proceeds. Also, pitot tube probes can be inserted in the air flow to measure static and dynamic air pressure.
