On the two-phase theory of fluidization
Web1 de fev. de 2024 · The division of gas flow and the gas exchange rate is crucial for the estimation of reactions between gas and particles [27]. With the assumption that the emulsion phase has a solids holdup of incipient fluidization and there are no particles inside bubbles, the two-phase theory overestimates of the gas flow in the bubble form [12]. Web28 de mar. de 2006 · The momentum and mass conservation equations derived in part 1 are used in the limiting case of large solids-to-fluid density ratio. Bubbles generally appear in such fluidized beds and solutions are obtained which describe the motion of the particulate and fluid phases in the presence of a fully developed bubble.
