溶質分散係数と間隙流速の関係に試料特性が与える影響

Influence of Material Properties on the Relation between Dispersion Coefficient and Pore-Velocity
File
Description
In order to investigate influence of material properties on the relation between dispersion coefficient D and pore-velocity v, a mass transfer test was performed with uinform grain-size and non-uniform grain-size(mixed together) glass beads.
From the results obtained, it was observed that relationship D-v was linear, and that the dispersion coefficient increased with grain-size and non-uinformity of grain-size distribution at the same pore-velocity. The relationship D-v was formulated using two parameters representing material properties. The experimental dispersion coefficient agreed with calculations.
