在内径0.152 m和0.305 m的循环流化床提升管中对纵向固体混合进行了实验研究。所用的表观气速和平均固体通量分别为2.8-5.0 m/s和5.0-80 kg/m 2 .s，并且床固体的表面体积平均直径为71μm，颗粒密度为2,456 kg/m 3 。脉冲注射实验中使用了氯化钠示踪剂。一维分散模型令人满意地描述了测量的固体混合
Longitudinal solids mixing was studied experimentally in circulating fluidized bed risers of internal diameter 0.152 m and 0.305 m. Superficial gas velocity and mean solids flux used were 2.8-5.0 m/s and 5.0-80 kg/m 2 .s, respectively, and the bed solids had a surface volume mean diameter of 71 μm and a particle density of 2,456 kg/m 3 . A sodium chloride tracer was used in impulse injection experiments. A one-dimensional dispersion model describes measured solids mixing satisfactorily
