| Abstract: | By using the optical fiber probes and pressure sensors, the axial pressure profiles and radial concentration profiles were investigated in a fast fluidized bed ( 140 mm ID ) with bluff-body. It was found that the concentration and pressure profiles are strongly affected by the bluff-body, and the gas-solid mixing in the bed radial direction is also greatly intensified. |
