E. Vanderknaap et al., EFFECT OF SEDIMENTATION ON THE FORMATION OF PARTICLE GELS - A COMPUTER-SIMULATION STUDY, Colloids and surfaces. A, Physicochemical and engineering aspects, 85(2-3), 1994, pp. 265-270
Aggregation of colloidal particles can lead to the formation of a part
icle gel. The formation of a gel can be disturbed by sedimentation of
the aggregating particles, which leads to the formation of a clear lay
er on top of the gel. In this study clear-layer formation is studied b
y computer simulation. The computer model used in this work is an exte
nsion of the model for cluster-cluster aggregation. The influence of s
edimentation rate and interparticle forces (sticking probability) on t
he height of the clear layer and the porosity of the gel (or sediment)
are evaluated.
