Abstract: The flow behavior of the bubble in gas/solid fluidized bed is studied in multi-scales.A hypotheses of taking dispersed bubble as the continuous medium and the hydromechanics expression based on volume flux are proposed.The mathematical model of radial porosity distribution in the dense zone is developed.The radial distribution of the porosity is parabolic in nature according to the theoretical calculation and the calculated data is consistent with experimental data satisfactorily.
