AbstractA special designed circulating fluidized bed setup has been constructed to study the hydrodynamics of gas-solids downflow operating at high solids concentration and high solids flux. The results show that the fluctuation of the transient solids concentration under high-density operating is gentle, and the radial distribution of the standard deviation of the transient solids concentration is relative uniform in the central region, while it decreases significantly in the peripheral region. The axial distribution of solids concentration is more uniform in the high-density downer, and the radial nonuniform core/annulus structure still exists in the high-density downer.
