The National Science Foundation (NSF) is offering a federal grant opportunity titled "Fluid Dynamics," aimed at supporting fundamental research in various fluid dynamics phenomena. The program encourages proposals that contribute to the scientific understanding of fluid dynamics through experiments, theoretical developments, and computational discovery, with major areas of interest including turbulence, bio-fluid physics, non-Newtonian fluid mechanics, and renewable energy applications. With an estimated total program funding of $9,175,000 and no cost-sharing requirements, proposals can be submitted at any time, and interested applicants can reach out to NSF grants.gov support at grantsgovsupport@nsf.gov for assistance.
