The effects of distributor design on the hydrodynamics within the entrance region of a cocurrent downflow circulating fluidized bed (downer) reactor

he effects of the gas and solids distributor design and operating conditions on the flow structure development and acceleration in the entrance region of a 9.3 m tall and 0.1 m i.d. gas-solid downflow reactor were studied using FCC particles.;The three distributors were designed as internals of the 0.2 m distributor shell so that modifications were more easily facilitated. Distributor...
