An experimental approach is proposed to investigate the gas-solid structure in the vicinity of a sparger nozzle in a fluidized bed. The local hydrodynamics were studied under injection velocities ranging between 0 and 100 m/s and three orientations. A fiber-optic probe was used to measure the instantaneous local particle holdup near the tip of the sparger nozzle. Under the investigated conditions, the local gas-solid structure was influenced on the measurement position, nozzle orientation and injection velocity. Four distinct zones were identified from the local particle holdup data, with the boundaries corresponding to characteristic jet lengths. Strong discrepancies were found with existing correlations. Further studies are required to achieve better jet length estimation and dynamic analysis of the gas-solid structure.
