WebApr 5, 2024 · This article is part of the NASA Knows! (Grades K-4) series. 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. http://turbulence-online.com/Publications/windtunnel/windtunnels.html

WebJan 13, 2012 · Corrsin ( 1963) suggested that, in order to avoid the influence of the walls on grid turbulence and ensure that an appreciable part of the tunnel satisfies the criterion for homogeneity, the ratio of the width or height ( H) of the wind tunnel to the mesh size ( M) should be much greater than one. For our experiment, H / M = 11.8. WebFeb 23, 2024 · The cryogenic wind tunnel achieves the required Reynolds number by reducing the viscous forces rather than increasing the inertial forces; even then the actual Reynolds numbers encountered in flight are rarely achieved and one has to resort to scaling laws. The scale of the model used depends on the application. myaged care.gov
