The grant is a subcontract from ATA Engineering, Inc., in collaboration with the Air Force Research Laboratory and Mississippi State University, funded under the Department of Defense High Performance Computing Modernization Program (HPCMP), specifically the HPCMP Applications Software Initiative (HASI) Project. They are working to develop enhanced computational fluid dynamics (CFD) models and algorithms to improve the prediction of flow and combustion in high-speed aircraft propulsion systems. Their focus at OU is the modeling and simulation of fluid turbulence. The team will be implementing newly developed models into the CFD software Loci-CHEM and providing the new tools to their collaborators at ATA and AFRL. This is the first year of a potentially four year project, subject to project progress and funding availability. The research group is hopeful to be awarded Year 2 funding.
