The National Science Foundation awarded a $274,770 Project Grant under the Engineering program (CFDA 47.041) to the University of Illinois to conduct collaborative research on the fundamental scaling of rotating wakes. The research aims to enable engineers to use small-scale models in lower-cost wind tunnels while still capturing the full-scale behavior of the flow, which can be applied to a broad range of rotary systems such as helicopters, drones, energy systems, and artificial heart pumps. The project integrates advanced computational approaches, including inverse blade design, large eddy simulation, and hybrid unsteady Reynolds-averaged Navier-Stokes methods, with extensive experimental campaigns in multiple wind tunnel facilities. The research will generate a publicly accessible database, advancing the fundamental understanding of rotary system wakes and providing critical insights for a variety of applications. The award period is from July 1, 2025, to June 30, 2028.
