Abstract
A particle dispersion model calculating local particle agglomeration characteristics of a solid/liquid suspension has been developed. In a model, not only the effects of Brownian and shear agglomerations and shear break-up but also the convective effects by local velocity components in a flow were taken into consideration. With this model, the local agglomeration characteristics in a suspension with various solid fractions were computed for a flow between parallel plates. The present model shows that the high agglomeration causes in a center region of the flow between parallel plates where low shear is added, and that the viscosity becomes high there. From this, it is concluded that the present model leads to a reasonable result on the particle agglomeration characteristics and a promised tool for estimating local particle agglomeration and viscosity characteristics in a flow.
