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

1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) 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. The team […]

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

1 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) 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. Professor Miljkovic will investigate […]
