Dewatering of concentrated flocculated suspensions in a screw press

加压过滤是从悬浮液中除去液体的重要方法。在模拟这种情况下，颗粒是软的和多孔的过程中出现的困难。这里的脱水是由两个不同的孔隙度尺度上发生的过程。虽然这类问题在自然和工程环境中很常见，但这项工作的动机源于纸浆加工中的纸浆和纸张应用。特别是，这项工作是与维美德（蒙特利尔）的合作伙伴关系，我们将检查脱水过程中的剪切效果。它是不列颠哥伦比亚省大学（UBC）和魁北克大学三河分校（UQTR）之间的合作伙伴关系。该项目将在四年的时间内，工作将由2名博士和2名本科生进行。

Pressure filtration is an important method for removing liquids from a suspension. Difficulties arise in modeling this process for cases where the particles are soft and porous. Here the dewatering is governed by processes occurring on two different porosity scales. Although this class of problem is commonly found in natural and engineering settings, the motivation of this work stems from a Pulp and Paper application in pulp processing. In particular, this work is a partnership with Valmet (Montreal) in which we will examine the effect of shear during dewatering. It is a partnership between the University of British Columbia (UBC) and the University of Quebec at Three Rivers (UQTR). The project will be over a four year period in which the work will be conducted by 2 PhD and 2 undergraduate students.
