| Abstract: | Mass transfer from assemblage of irregularly shaped particles to fluid was analysed using a combination of “cell” and “channel” concepts. The theoretical analysis predicts that blending active grains with inert spheres will result in an enhancement of the mass transfer due to a decrease of the overlapping of the neighbour particles and to a change of the bed geometry. The comparison between the derived relationship and available literature and our own experimental data shows a reasonably good agreement. |
