The Fluids in Advanced Systems and Technology (FAST) Group is a computational and experimental thermal hydraulics group focused on enabling the development of advanced energy systems. This group utilizes and develops high fidelity computational fluid dynamics (CFD) and reduced-order design tools intended for nuclear, solar and geothermal power plants. The FAST Group conducts experimental activities for investigating fundamental phenomena in fluid systems, generating new correlations for design related data of fluid systems (heat transfer coefficients and pressure drop), and creating validation data for high fidelity CFD methods.
Investigating cross flow in a Molten Salt Reactor heat exchanger tube bundle is useful for learning about pressure losses and heat transfer occurring in the bundle. This information can then be used for design and optimization of compact heat exchangers for molten salt reactor applications.
Investigating flow across a cylinder is useful for learning about pressure distributions on the cylinder and eventually heat transfer from cylinder to the fluid. This can be extended to learning about flow in heat exchangers, flow over a wing, and wind loading on a building.

The Computational Energy-Material-Interaction Laboratory (CEMIL) focuses on the interaction of intense energy fluxes such as radiation, plasma, particle and laser beams with materials and prediction of material behavior and properties under extreme pressures and temperatures. The research areas include modeling of thermodynamic, optical, and electrical properties of Warm Dense Plasmas; computational studies of the internal charging of dielectric and insulating materials of a spacecraft under the impact of Jovian electrons and photons (Europa Lander project); modeling of ultrafast laser-material interactions at an atomic level, nature and behavior of materials in a highly non-equilibrium state; and theoretical analysis and computational modeling of macroscopic melt splashes and losses from metallic divertor plates and wall materials in fusion devices such as ITER.
