Literature review format for thesis. this paper describes a research carried out for the design of a wind mill tower reduced- scale model to be built and tested in the boundary layer wind tunnel at the university of la coruña. applications of wind- tunnel research range from routine testing of airframes to fundamental research on the boundary layer, the slow- moving layer of air adjacent to any wind- exposed body surface. measurements of air pressure and other characteristics at many points on the model yield information about how the total wind load is distributed. the present paper deals with a study of very small- scale open- loop wind tunnel design and test.
to verify the proposed design criteria, an open- circuit small- scale wind tunnel was built and tested. the designed wind tunnel is composed by a settling chamber, a contraction section, a test section, a diffuser as well as a fan. a vision in aeronautics" the wind tunnel project white paper. a project between the nasa lewis research center' s learning technologies project and the general benjamin o. aviation high school, a cleveland public school report created by: jack gilbert, general benjamin o. aviation high school and beth lewandowski, nasa lewis research center. more wind tunnel research paper ordinated ground based wind tunnel experiments in low speed facilities. for illustrative purposes three specific examples of in- flight high lift building block flow experiments capable of yielding a high payoff are described. the report concludes with a description of a joint wind tunnel / flight test approach to high lift aerodynamics research. the wind tunnel is a large experimental apparatus that is used frequently for aerospace engineering research as well as undergraduate class projects.
