The Department of Defense, specifically the Navy, is seeking proposals for the development of hypersonic computational fluid dynamics (CFD) heat flux sub-models as part of the Small Business Innovation Research (SBIR) program. The objective is to enhance modeling and simulation of Navy-relevant hypersonic flows by creating or improving turbulence-heat flux sub-models that can be integrated into existing CFD solvers, demonstrating improved predictive capabilities through verification and validation against hypersonics datasets. This initiative is crucial for advancing the accuracy of heat flux predictions in hypersonic environments, which has significant implications for both military applications and commercial sectors such as turbomachinery and internal combustion engines. Interested parties should note that the solicitation will open on April 23, 2025, with proposals due by May 21, 2025, and can find more information at the official DOD SBIR/STTR website.
