Abstract Hydrodynamics of gas flow of cocurrent downflow of gas-solid mixture was investigated in a downcomer of 110mm ID equipped in a circulating Fluidized Bed by means of tracer gas technique with helium gas for two kinds of particle. A new gas flow equation deduced from the analysis of the interaction beween gas and solid was given. The predicted results of this equation were in good agreement with experimental data.
