Fluid Dynamics Research to Accelerate Combustion Science

  • Code: RAPTOR
  • Science Domain: Engineering/Combustion
  • PI: Joseph Oefelein, Sandia National Laboratories


Joseph Oefelein of Sandia National Laboratories heads a team focused on using the computational fluid dynamics code RAPTOR to explore the chemical and physical processes of combustion. Optimizing RAPTOR for Summit’s hybrid architecture will enable an entirely new generation of high-fidelity simulations that identically match engine operating conditions and geometries. Such a scale will allow direct comparisons to companion experiments, providing insight into transient combustion processes such as thermal stratification, heat transfer, and turbulent mixing. Ultimately, this work will help inform new design concepts of internal combustion engines and gas turbines, which have the potential to provide significant increases in fuel efficiency with minimal emissions.
