摘要：
Circulation of fludized particles in side regions was studied in two-dimensional tapered beds with apex angles of 30-degrees and 45-degrees and an inlet cross section of 40mm x 40 mm. Colored particles were used as tracer and solid movement in the tapered bed was observed. The circulation rate of solid particles was measured from the descent of tracer particles. Steady circulation of fluidized particles was observed between the core and side regions. Incipient circulation velocity u(B) was measured and estimated. Circulation rate of particles v0 increased with excess gas velocity (u(i)-u(B)). The estimations of this rate agreed well with experimental results.
