摘要9729041 G. Klinzing，匹兹堡大学这是匹兹堡大学和陶氏化学公司之间的一个GOALI项目。 本建议的目的是提供通过管道的数据从一个大规模的系统的基础上的高浓度的气固流的基本理解。 众所周知，小规模的实验室设施不能完全再现大工业规模的气固输送现象。 水平和垂直密相气力输送中的流型将作为材料性质和操作条件的函数，使用3和4英寸的管道和特定的密相流实验工具进行研究。 合作伙伴包括其他工业单位（陶氏、MAC、杜邦、伊士曼、巴布科克等）和英国领先的研究团体。和日本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，电子层析成像，以及统计和模糊逻辑分析方法。 测试材料将由工业咨询委员会确定，以代表工业应用。 该项目如果成功，将为基于基本材料性质以及粉末和流体力学原理的大规模工业密相输送系统的性能计算提供预测方法。 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. ***
