INFLUENCE OF BUBBLE-BUBBLE INTERACTIONS ON THE MACROSCALE CIRCULATION PATTERNS IN A BUBBLING GAS-SOLID FLUIDIZED BED

摘要

The macro-scale circulation patterns in the emulsion phase of a gas-solid fluidized bed in the bubbling regime have been studied with a 3D Discrete Bubble Model. It has been shown that bubble-bubble interactions strongly influence the extent of the solids circulation and the bubble size distribution.
