WebOct 11, 2024 · The GMFP consists of a thin elastic membrane encasing granular material, such as sand, metal powder, plant seeds, etc. When applying load to the GMFP, the granular medium undergoes the jamming transition [2,3].The result of this is fluid-like behavior [4,5] of the GMFP, when unloaded or approaching the substrate topography … WebJun 30, 2024 · In this study, the multi-phase Eulerian–Eulerian two-fluid method (TFM) coupled with the kinetic theory of granular flow (KTGF) was used to investigate the hydrodynamics of particle flows (Geldart Group B) in a lab-scale bubbling fluidized bed. The goal was to improve the bubble flow behavior inside the fluidized bed to improve the …
