Pressure filtration of soft porous fibre suspensions (Phase 2)

加压过滤是从悬浮液中去除液体的重要方法。对于颗粒柔软和多孔的情况，对这一过程进行建模会遇到困难。尽管这类问题在自然和工程环境中普遍存在，但这项工作的动机源于纸浆和造纸在纸浆加工中的应用。特别是，这项工作是与Valmet(蒙特利尔)的合作，我们将以与工业水平相当的速度检查一维加压过滤，并对微尺度上发生的动态进行建模。模型预测将与试点工厂的数据进行比较。该项目将在四年内由1名PDF、1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 1D pressure filtration at rates comparable to industrial levels and model the dynamics occurring at the microscale. Comparisons of the model predictions will be made to pilot plant data. The project will be over a four year period in which the work will be conducted by 1 PDF, 1 PhD and 2 undergraduate students.
