Noninvasive measurements of gas exchange in a three-dimensional fluidized bed using hyperpolarized 129Xe NMR
Tina Pavlin, Ruopeng Wang, Ryan McGorty +5
We present a novel NMR technique that provides a non-invasive, direct measurement of gas exchange in a three-dimensional gas-fluidized bed of solid particles. The NMR spectrum of h…
Using NMR to Validate First-Principles Granular Flow Equations
D. Candela, C. Huan, K. Facto +3
Nuclear magnetic resonance (NMR) experiments are described for two granular-flow systems, the vibrofluidized bed and the gas-fluidized bed. Using pulsed field gradient, magnetic re…
Applications of controlled-flow laser-polarized xenon gas to porous and granular media study
R. W. Mair, R. Wang, M. S. Rosen +3
We report initial NMR studies of continuous flow laser-polarized xenon gas, both in unrestricted tubing, and in a model porous media. The study uses Pulsed Gradient Spin Echo-based…
Diffusion NMR Methods Applied to Xenon Gas for Materials Study
R. W. Mair, M. S. Rosen, R. Wang +2
We report initial NMR studies of i) xenon gas diffusion in model heterogeneous porous media, and ii) continuous flow laser-polarized xenon gas. Both areas utilize the Pulsed Gradie…
