On-line generation and error handling for surrogate models within multifidelity uncertainty quantification (PI)

  • Goal: This project aims to integrate reduced-order model methods within a multifidelity uncertainty quantification framework and to demonstrate the greater efficiency and generality of this approach for several test problems with respect to their state-of-the-art counterparts.
  • Sandia collaborators: Gianluca Geraci (Co-PI), Mike Eldred, Kevin Carlberg.
  • External collaborators: Francesco Rizzi (NexGen).
  • Research topics: nonlinear model reduction; uncertainty quantification
  • Funding source: Sandia National Laboratories’ Laboratory-Directed Research & Development.

Rapid high-fidelity aerothermal responses with quantified uncertainties via reduced-order modeling

  • Goal: This project aimes to enable high-fidelity aerothermal simulations of hypersonic vehicles to be employed (1) to generate large databases with quantified uncertainties and (2) for rapid interactive simulation.
  • Sandia collaborators: Kevin Carlberg (PI), Micah Howard, Jeff Fike.
  • External collaborators: Francesco Rizzi (NexGen), Karen Willcox (UT Austin).
  • Research topics: nonlinear model reduction; uncertainty quantification; hypersonic vehicles

Revolutionizing systems-component design via advanced uncertainty quantification and reduced-order modeling

  • Goal: This project aims to enable rapid design evolution, concept exploration, and prototyping of complex system components while (1) ensuring designs satisfy all system-level requirements and (2) rigorously accounting for underlying uncertainties.
