Closed‐form expressions are presented for predicting vertical concentration distribution of the dispersed phase in the turbulent core of pipe and channel flow. Experimental data obtained with spherical particles, of mean diameter d 50 comparable to the Kolmogorov microscale, are in good agreement with model predictions. The average value of dimensionless lateral particle diffusivity, ζ = ε/ Ru * , determined from these data is approximately 0.25, that is, fairly close to previously reported measurements with much coarser particles.
