A first principles-based model was developed for a transcritical C02 gas cooler, using a finite element method. The model uses published correlations for refrigerant and airside heat transfer and pressure drop. Experimental ...

We model the radial segregation patterns that form in a thin rotating drum partially filled with beads of two sizes. We predict that the waviness (or amplitude-to-wavelength ratio, denoted w) of a pattern should be subjected ...

Radiation-enhanced diffusion (RED) of a Nd buried tracer layer in UO2 thin films was measured with Secondary Ion Mass Spectrometry (SIMS). Samples were irradiated with 1.8 MeV Kr+ over a temperature range from 400 to 800 ...

This thesis discusses a gas around a thermal source that emits particles with a temperature that is high enough for the emitted particles to self-interact. Particles emitted from a hot thermal source by means of Hawking ...
