The focus of the present work is the study of separation or fractionation of different classes of non-Brownian particles in a yield stress fluid. The motivation for the present work stems from an interest in one particular particle suspension, i.e. papermaking fibre suspensions. Papermakers fractionate to allow targeted processing of the low quality fraction to improve product performance while minimizing the amount of processing and subsequent energy, chemicals and capital required. The pulp fractions can also be used to produce papers with radically different properties.

本工作的重点是研究屈服应力流体中不同类别的非布朗粒子的分离或分馏。本工作的动机源于对一种特定颗粒悬浮液，即造纸纤维悬浮液的兴趣。造纸商可以对低质量部分进行有针对性的加工，以提高产品性能，同时最大限度地减少加工量和后续所需的能源、化学品和资本。 纸浆部分也可用于生产具有完全不同性质的纸张。
