论文摘要
研究了胶体悬浮液以及其流变学与微观结构之间的关系。文献表明了流变量和粒子体积分数之间关系的充分证据，忽略了集群的影响。我们建议使用新的双分形结构扩展先前的模型，该结构首先允许在渗透系统的情况下恢复众所周知的模型，其次，捕获了群集大小的影响。这个新模型强调了这种结构以说明最近实验结果的必要性。然后，将模型与文献的数据进行比较，并显示了密切的一致性。
Colloidal suspensions and the relation between their rheology and their microstructure is investigated. The literature showed great evidence of the relation between rheological quantities and particle volume fraction, ignoring the influence of the cluster. We propose to extend previous models using a new double fractal structure which allows, first, to recover the well-known models on the case of percolated system and, second, to capture the influence of the cluster size. This new model emphasises the necessity of such structure to account for recent experimental results. Then, the model is compared with data coming from the literature and shows close agreement.
