Open vs closed wind tunnel
Web5 de abr. de 2024 · Wind tunnels are large tubes with air moving inside. The tunnels are used to copy the actions of an object in flight. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are big enough to hold full-size versions of vehicles. WebBoth open-circuit, anechoic wind tunnels, and closed-circuit wind tunnels are used for aerodynamic and aeroacoustic studies of various flow-induced noise phenomena. The choice of test facility is driven primarily by the type of application, the design speed, and the desired model scale.
