摘要

Radial profiles of fine particle (36 μm) concentration and velocity in a riser of 140 mm inner diameter are investigated using a dual-beam optical density sensor and a Laser Doppler Velocimeter. According to the cross-sectional average solids fraction there are three different kinds of radial solids fraction profiles: the uniform shape, the dense ring form and the aggregation form. At high superficial gas velocity and low solids concentration, the radial profile of fine particle velocity obeys 1/7 power law of turbulent flow. Comparing the solids concentration and velocity profiles with those of 54 μm FCC particle, the radial profiles of solids fraction and velocity become flatter as the particle size decreases.
