国家科学基金会-化学和安防运输系统颗粒和多相工艺计划分部(1415)摘要建议编号：CTS-0553856主要调查者：Klining，George EAffiliation：匹兹堡大学建议标题：GOALI：Three Plug Model本建议旨在全面了解动态塞子通过输送系统时的结构。通过三个研究小组的合作，两个在匹兹堡大学和内盖夫的本古里安大学，一个来自工业的陶氏化学公司，将汇集人才和经验来探索塞子结构的前沿，为产业界和学术界之间的联系提供独特的合作。智力价值拟议的研究将通过应用实验和建模努力来开发塞子上的信息库的广度和深度，调查塞子周围的摩擦分布，并将关联的塞子的法向载荷与摩擦分布相耦合，来深入研究塞子的行为和结构。将输送颗粒的吸力、塞子的内部结构以及移动塞子和静止的颗粒沉积层之间施加的摩擦力与力平衡模型的预测进行比较。该奖项将提供学术研究人员和工业合作伙伴之间互动的机会。它可以对气力输送系统的设计产生重大影响，无论是在公司内部还是在更广泛的行业层面都是如此。这次合作是利用工业规模的输送实验室进行基础研究的独特机会。这项研究将通过在密相输送系统的基本理解和设计方面的密切互动，为学生的学习、教师队伍的增强和工业的丰富提供一个丰富的环境。

National Science Foundation - Division of Chemical &Transport Systems Particulate & Multiphase Processes Program (1415)ABSTRACTProposal Number: CTS-0553856Principal Investigator: Klinzing, George EAffiliation: University of PittsburghProposal Title: GOALI: Three Plug ModelThis proposal is targeted to a complete understanding of the structure of dynamic plugs as they move through a conveying system. Through collaboration of three research groups, two based at universities The University of Pittsburgh and Ben-Gurion University of the Negev, and one from industry The Dow Chemical Company, talent and experience will be pooled to explore the frontier of plug structures, providing a unique collaboration for linkages between industry and academia.Intellectual MeritThe proposed study will delve into the plug-flow behavior and structure by applying experimental and modeling efforts to developing the breadth and depth of the information base on the plug, investigating the frictional distribution around the circumference of the plug, and coupling the associated normal load of the plug to the frictional distribution. The pick-up forces for particles being conveyed, the internal structure of the plug and the friction that is exerted between the moving plug and the stationary deposited layer of particles will be compared to predictions from a force balance model.Broader ImpactThis GOALI award will provide the opportunity of interaction between academic researchers and an industrial partner. It can have a significant impact on the design of pneumatic conveying transport systems, both within the company and on a broader industrial level. The collaboration is a unique opportunity to use the industrial scale conveying laboratory for fundamental studies. The research will provide a rich environment for student learning, faculty enhancement and industrial enrichment through an intimate interaction in the fundamental understanding and design of dense-phase conveying systems.
