GOALI: Fundamental Study of Dense Phase Conveying

摘要9729041匹兹堡大学G·克林津这是匹兹堡大学和陶氏化学公司之间的一个目标项目。本提案的目的是根据来自大型系统的数据，对管道中高度浓缩的气固两相流动提供基本的理解。众所周知，小型实验室设备不能完全再现大规模工业规模的气固两相输运现象。利用3英寸和4英寸的管子和特定的密相流实验工具，研究了水平和垂直密相气力输送中的流型随材料性质和操作条件的变化。合作包括英国和日本的其他工业单位(陶氏、MAC、杜邦、伊士曼、巴布科克等)和领先的研究小组。实验工具包括颗粒塞和剪切测试仪、压力波动传感器、快速视频、电层析以及统计和模糊逻辑分析方法。被测试的材料将由一个工业咨询委员会确定，以便在工业应用中具有代表性。该项目如果成功，将为基于基本材料性质、粉末和流体力学原理的大型工业密相输送系统的性能计算提供一种预测方法。研究生将在学术和工业设施中进行研究。***

Abstract 9729041 G. Klinzing, University of Pittsburgh This is a GOALI project between University of Pittsburgh and The Dow Chemical Company. The objective of this proposal is to provide basic understanding of highly concentrated gas-solid flows through pipes based on data from a large-scale system. It is well known that small-scale laboratory facilities cannot fully reproduce gas-solids transport phenomena in large industrial scale. The flow patterns in horizontal and vertical dense phase pneumatic transport will be investigated as a function of the materials properties and operating conditions using 3 and 4 inch pipes and specific experimental tools for dense phase flow. Collaborations include other industrial units (Dow, MAC, DuPont, Eastman, Babcock, and others) and leading research groups in U.K. and Japan. The experimental tools include particle plug and shear testers, pressure fluctuation transducers, fast video, electrical tomography, as well as statistical and Fuzzy logic analysis methods. The tested materials will be determined by an industrial advisory board in order to be representative for industrial applications. The proposed project, if successful, will provide a predictive method for calculating the performance of large scale industrial dense phase conveying systems based on the fundamental materials properties, and principles of powder and fluid mechanics. Graduate students will perform their research in both the academic and industrial facilities. ***
