ABSTRACTProposal Number: CTS-0209928Principal Investigator: Heindel, TheodoreAffiliation: Iowa State UniversityTitle: GOALI - Gas Holdup in Flocculating SlurriesThe effect of fiber geometry and mass fraction on gas holdup in gas-liquid-fiber slurries will be investigated by the PI at Iowa State University and the PI at Kimberly-Clark Corporation. The most direct application of the results is to fiber de-inking and fiber bleaching in fiber floatation columns used in many pulp and paper producing companies. Previous results from independent investigation of the PIs have shown interesting behavior when fiber is added to a gas-liquid column. The gas holdup in the slurry can be significantly different with the presence of fiber. The proposal study will investigate the various aspects of this problem including the effect of fiber entanglement on gas holdup.

摘要提案编号：CTS-0209928首席研究员：Heindel，Theodore所属单位：爱荷华州州立大学标题：GOALI -絮凝浆液中的气含率纤维几何形状和质量分数对气-液-纤维浆液中气含率的影响将由爱荷华州州立大学的PI和Kimberly-Clark Corporation的PI进行研究。 研究结果最直接的应用是在许多制浆造纸公司使用的纤维浮选柱中的纤维脱墨和纤维漂白。 以前的独立调查的PI的结果表明，有趣的行为时，纤维添加到气液柱。 浆料中的气含率可随着纤维的存在而显著不同。 这项研究将调查这个问题的各个方面，包括纤维缠结对气含率的影响。
