Abstract:Although cryogenic wind tunnels are typically used in industry for transonic testing, Ludwieg tunnels with high charge tube pressures can also produce unit Reynolds numbers high enough to match in-flight conditions. A brief timeline of transonic Ludwieg tunnel development is presented that shows how it was nearly selected for full-scale construction to compliment the National Transonic Facility. Having recently been refurbished, an overview of the unique high Reynolds number facility at UT Arlington is present… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
