Bubble Dynamics and Dense Phase Composition in 2-D Binary Gas-Solid Fluidized Bed
Gas-solid bubbling fluidized bed with binary particles is a potential candidate for performing the dry coal beneficiation process due to its advantages such as the ability to adjust separation density and the elimination of process water. A two-dimensional (2D) fluidized bed was used to study …

Identification and Distribution Analysis of the Mid-phase in a Low-velocity Gas-solid Fluidized Bed
The intermediate phase in low-velocity gas-solid fluidized beds generally presents excellent gas-solid contact in the systems. However, no comprehensive understanding of this vital phase is available in the literature. Therefore, this study proposed a statistical method to identify this …
