OSU High-Speed Direct Numerical Simulation Software

NASA's Shared Services Center has issued a Special Notice for a sole source contract opportunity to acquire OSU High-Speed Direct Numerical Simulation Software from Ohio State University. The procurement is specifically intended for Professor Lian Duan and his team at Ohio State University to provide Direct Numerical Simulation (DNS) codes for studying laminar-turbulent transition in hypersonic boundary layer flows. The contract will support NASA Langley Research Center's 31 Inch Mach 10 Tunnel facility and is classified under NAICS Code 611310 for educational institutions. Performance will occur at NASA Langley Research Center, with the procurement conducted under FAR Parts 12 and 13 for commercial items. This is explicitly designated as a sole source requirement, meaning NASA intends to award the contract without competition.

The primary objective is to obtain specialized DNS software capable of simulating flow and freestream disturbance environments in rectangular cross-section nozzles designed for hypersonic Mach numbers, ultimately improving predictive capabilities for high-speed flight vehicle design. Interested organizations may submit capability statements and qualifications to the contracting officer, Shanna Patterson, by 7:00 AM Central Standard Time on July 3, 2025. The contract period of performance runs from July 10, 2025, through September 30, 2025, requiring delivery of DNS codes with verified solid-wall boundary conditions and associated preprocessing/postprocessing utilities. NASA's justification for sole source selection emphasizes Professor Duan's unique expertise and previously validated DNS codes for similar nozzle configurations, arguing that alternative vendors would require substantial time and resources to develop comparable capabilities. The government retains discretion to determine whether to proceed competitively based on capability submissions received, though the clear intent is to proceed with the sole source award to Ohio State University.
