Abstract:In the present study, flow visualizations and quantitative measurements around a NACA0012 airfoil are performed under air and CO2 operation modes. A diaphragmless shock tube system is used for a high-subsonic airfoil testing. This system has the possibility of efficient aerodynamic experiments as an intermittent wind tunnel. A point diffraction interferometry (PDI) is used for a flow measurement technique. Moreover, the comparison with numerical results by the OpenFOAM is performed. The driver tube of this sho… 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.
