Modeling Heat Transfer and Densification during Laser Sintering of Viscoelastic Polymers
… forces was developed. The powder-bed temperature was approximated using the thermal model developed herein. The effect of the enthalpy of melting for semi-crystalline polymers was accounted for using a temperature recovery approach. Time-temperature superposition was used to account …

Evaluation of environmental materials as thermal witness materials
… i.e. good description of spatial and temporal temperature distribution. Temperature measurements in pyrotechnical events are especially challenging, where the temperature of the environment rises more than 2000 K on microseconds to few milliseconds time scale. These environments produce high …

Modelling and Experimental Characterization of Solar-Assisted Ground Source Heat Pump Systems with and without Thermal Energy Storage for Cold Climates
… injected back. This can potentially cause ground temperature decline, gradual performance reduction and possibly eventual failure. The associated ground thermal imbalance and the high initial cost of a GSHP are major challenges to the wider adoption of this clean energy technology. In addition, …

Multi-Fidelity Study of Complex Multi-Scale Flows Concerning Stagnation Probes
… of these losses. The measurement of stagnation temperature is an important performance metric for the calculation of component efficiency in aero-engines, particularly due to reductions in the margin of error over concurrent improvements in jet engine performance and measurement techniques. …

Advancing Lithium Extraction from Nevada’s Sedimentary Claystones: Hydrometallurgical Pathways and Sustainability Perspectives
… (DOE) framework to evaluate the effects of temperature, acid concentration, leaching time, and solid-to-liquid ratio across two mineralogically distinct Nevada claystone types, is investigated. Under optimized conditions, near-complete lithium extraction (~100%) was achieved. Kinetic …
