dc.description.abstract | Flow behavior of gas bubbles, liquid and particles, and mixing in the liquid phase were studied in draft and annulus of a draft tube gas-liquid-solid fluidized bed. The experimental unit was a 80mm ID × 1.5 m column with an 50mm ID internal draft tube. A 2-D unit of the same size and geometry was used to assess the local concentrations and velocities of liquid, particles and air bubbles. Fluid and particle dynamics in the draft and annular regions were analyzed using the drift-flux model extended to the 3- phase flow, and in terms of the effective buoyancy of solid particles. Liquid mixing was studied based on the tracer-response technique, using the model of axial dispersion. | en |
