✦ Synopsis

Particle Peclet numbers ranging from 0.056-O. 198 were calculated from tracer response measurements in a three-phase fluid&d bed consisting of air, water, and alginate beads. Diffusion of the calcium chloride tracer into the beads was measured and found to follow Fick's Law. If unaccounted for, intraparticle tracer difision was shown to cause a 20% underprediction of Peclet number.
