Abstract:
Local flow structure of a fluidized bed was studied. For this purpose, particles velocity and concentration were measured in a 152 mm ID bed. To measure these parameters, fiber optic probe with minimum interference in flow was used. This probe was consisted of 4 emitting and 3 receiving fibers arranged in an alternating array. To calculate velocity and concentration of particles, corresponding calibrations for each one was implemented. Radial changes in particle velocity showed that the direction of particles movement is mostly downward near the wall and upward at the centre. In addition, particles aggregation near the wall is more than the centre
