Pressure filtration of soft porous fibre suspensions (Phase 2)

压力过滤是从悬浮液中去除液体的重要方法。在颗粒柔软多孔的情况下，对这一过程进行建模会遇到困难。虽然这类问题通常在自然和工程环境中发现，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，这项工作是与维美德（蒙特利尔）的合作伙伴关系，我们将以与工业水平相当的速度检查一维压力过滤，并模拟微观尺度上发生的动态。将把模型预测结果与试验工厂的数据进行比较。该项目为期四年，由1名博士生、1名博士和2名本科生进行研究。

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.
