Continuous Bending-mode Elastocaloric Composite Refrigeration System for Compact, Lightweight, High-Efficiency Cooling

Nenad Miljkovic University of Illinois at Urbana-Champaign Traditional elastocaloric refrigeration systems are based on uniaxial compression of the elastocaloric material which makes them highly constrained by actuator requirements, the physics of column buckling, and limited surface area for heat transfer.

Physics-based Modeling and Tool Development for the Characterization and Uncertainty Quantification of Crater Formation and Ejecta Dynamics due to Plume-surface Interaction

David Scarborough Auburn University Professor Scarborough will develop and implement tools to extract critical data from experimental measurements of plume surface interaction (PSI) to identify and classify dominant regimes, develop physics-based, semi-empirical models to predict the PSI phenomena, and quantify the uncertainties.

Integrating Data-Driven and Physics-Based Models for Plume-Surface Interaction Predictions

Laura Villafane University of Illinois at Urbana-Champaign Rocket engine exhaust during lunar landings can blow away a large amount of lunar regolith causing damage to nearby hardware and the landing spacecraft itself. The complex physics governing this behavior is not well understood making it hard to predict and mitigate its effects.
