The Center for Radiative Shock Hydrodynamics (CRASH) is advancing predictive science in the nationally important area of radiation hydrodynamics (RH) via a unified, multi-prong approach. To substantially improve the ability to do predictive simulations of high - energy - density and astrophysical flows, Center researchers are:
- Developing a software framework for RH to serve as a testbed for development, verification and validation of RH modeling elements.
- Developing a system for hierarchically validating the software framework.
- Extending an existing experimental effort, centered on radiative shocks, to obtain data and quantify uncertainties in the experiments.
- Simulating these experiements and quantifying the accuracy of the simulations.
- Establishing a doctoral program for Predictive Science and Engineering.
The CRASH team, comprised of researchers from the University of Michigan and Texas A&M University, are experts in:
- Numerical methods for fluids, plasmas, and radiation transport
- Uncertainty quantification and propagation
- High - energy - density physics experiments and theory
- Applied mathematics
- Software engineering and computer science
- Parallelization of radiation transport algorithms
The potential impacts of the project include NNSA lab use of advanced methods in radiation hydrodynamic simulations and methods for uncertainty quantification developed in the Center and the hiring by the laboratories of people trained in predictive radiation hydrodynamics through the Center.
CRASH is funded by grants from DoE NNSA.
