This research program will result in the ability to design high-performance pulp processing systems that cantailor fibre properties by removing debris, and by fractionating and selectively refining fibres to createhigh-value paper products. The program objectives include development of fundamental screening knowledge,understanding of how novel features of the screen cylinder and rotor increase debris removal, and thedevelopment of a fractionation and refining model that predicts the effects of varying old corrugated cardboardtreatments on linerboard properties. This research supports the Canadian pulp and paper industry and builds onthe existing partnership between UBC and Aikawa Fiber Technologies (AFT), producer of pulp screeningcomponents. It extends the group's previous research work and expertise in the areas of fluid dynamics ofscreening, low consistency (LC) refining, pressure screen fractionation, and fractionation-LC refining systems.The proposed research program consists of one PhD project and one Master's project with two parts. The PhDproject will focus on modeling and simulation of screening and LC refining specialty products. The master'sproject, with two consecutive students, will focus on screen cylinder design and optimization through thesimulation of fibre and debris trajectory, as well as modelling of screen efficiency and capacity.Innovative high performance pulp processing system design will be trialed at pilot and mill scale and laterimplemented in the Canadian industry, which will enable Canadian pulp and paper companies to improve thequality and value of the products they produce. This new understanding will lead to advanced cylinder designsthat will ensure the long term competitive advantage of AFT, an advanced global manufacturing company withmajor a manufacturing facility in Sherbrooke, Quebec.

这项研究计划将导致设计高性能纸浆处理系统的能力，通过去除碎片，并通过分级和选择性地精炼纤维来调整纤维性能，以生产高价值的纸产品。该计划的目标包括开发基础筛选知识，了解筛鼓和转子的新功能如何增加碎片去除，以及开发分馏和精炼模型，预测不同旧瓦楞纸板处理对箱板纸性能的影响。这项研究支持加拿大纸浆和造纸工业，并建立在UBC和纸浆筛选组件生产商Aikawa Fiber Technologies（AFT）之间的现有合作关系基础上。该项目是本课题组在流体动力学、筛分、低浓磨浆、压力筛分级和分级-LC精炼系统等领域的研究成果和专业知识的延伸。该博士项目将侧重于筛选和LC精制特种产品的建模和模拟。该硕士项目，与连续两名学生，将侧重于筛筒设计和优化，通过模拟纤维和碎片的轨迹，以及建模的筛选效率和能力。创新的高性能纸浆处理系统设计将在试点和工厂规模和laterimplemented在加拿大的行业进行试验，这将使加拿大纸浆和造纸公司提高他们生产的产品的质量和价值。这种新的理解将导致先进的气缸设计，这将确保长期的竞争优势的AFT，一个先进的全球制造公司与主要的制造设施在舍布鲁克，魁北克。
