One of the goals of NASA’s Rotary Wing Project is to develop accurate multidisciplinary design analysis and optimization tools for new civil rotorcraft concepts using high-fidelity computational fluid dynamics (CFD) codes. CFD simulations of experimental rotor hover tests help researchers improve and validate the accuracy of the computational models and help engineers design better wind tunnel experiments.<\/p>\n<p>This visualization shows a pre-test hover simulation of a rotor within the 80×120-foot test section of the National Full-Scale Aerodynamics Complex at <a href=\"https:\/\/www.nasa.gov\/ames\">NASA’s Ames Research Center<\/a> in Moffett Field, California. The vortex wake is colored by vorticity, the wind tunnel floor is colored by pressure (with red as high and blue as low), and flow streamlines on the floor are shown in white.
