Experiment and simulation of high-speed gas jet penetration into a semicircular fluidized bed
William D. Fullmer, Jonathan E. Higham, Roberto Porcu +4
This work marks the third in a series of experiments that were in a semi-circular, gas-fluidized bed with side jets. In this work, the particles are 1 mm ceramic beads. The bed is…
Magnetohydrodynamic wave mode identification in circular and elliptical sunspot umbrae: evidence for high order modes
A. B. Albidah, V. Fedun, A. A. Aldhafeeri +7
In this paper we provide clear direct evidence of multiple concurrent higher order magnetohydrodynamic (MHD) modes in circular and elliptical sunspots by applying both Proper Ortho…
Anomalous Diffusion in a Bench-Scale Pulsed Fluidized Bed
Jonathan E. Higham, Mehrdad Shahnam, Avinash Vaidheeswaran
We present our analysis on micro-rheology of a bench-scale pulsed fluidized bed, which represents a weakly confined system. Non-linear gas-particle and particle-particle interactio…
Proper Orthogonal and Dynamic Mode Decomposition of Sunspot Data
A. B. Albidah, W. Brevis, V. Fedun +5
High resolution solar observations show the complex structure of the magnetohydrodynamic (MHD) wave motion. We apply the techniques of POD and DMD to identify the dominant MHD wave…
On the Dynamics of a Quasi-Two-Dimensional Pulsed-Fludized Bed
Jonathan E. Higham, Mehrdad Shahnam, Avinash Vaidheeswaran
Periodic fluidization of solids in a gas medium can generate structured bubbling patterns. This phenomenon has been successfully reproduced in fluidized bed systems called pulsed-f…
