The understanding of the mechanism of wall‐to‐bed heat and mass transfer in liquid‐fluidized beds requires knowledge of the effect of the motion of individual particles on transfer processes. Experimental studies on the enhancement in mass transfer due to motion of a particle in the proximity of the transfer surface are presented. Mathematical relations based on a mechanistic model are obtained to describe the variation of the enhanced rate with time. The model parameters are correlated in terms of the particle Reynolds number, the wall‐to‐particle distance, and an interaction parameter that accounts for the background fluid motion. The results of this work would be of use in modeling transfer processes in other liquid‐solid systems.
