An experimental and theoretical programme of research to resolve major obstruction-to-flow problems in bins and stockpiles

一项实验和理论研究计划，以解决垃圾箱和堆积物中的主要流动障碍问题。澳大利亚的许多工业依赖于矿物、化学品、食品、农产品和医药等散装固体材料的高效储存和处理。处理过程往往效率低下，以至于影响了行业的经济。在这里，我们提出了两个项目，以解决由于稳定的障碍物，如“鼠洞”造成的低效，以及由细粉的不寻常流动特性引起的实验低效。主要目标是使用实验和先进的数学建模技术，产生可靠的设计模型，最大限度地减少稳定障碍物的发生，并为提高细粉流量提供可靠的方法。

An experimental and theoretical programme of research to resolve major obstruction-to-flow problems in bins and stockpiles. Many of Australia's industries rely on the efficient storage and handling of bulk solids materials such as minerals, chemicals, food-stuffs, agricultural products and pharmeceuticals. Often the handling processes are inefficient to the extent of affecting the economics of the industry. Here we propose two projects addressing those inefficiences resulting from stable obstructions, such as "rat-holes", and those experimental arising from the unusual flow characteristics of fine powders. The major objectives are to use experimental and advanced mathematical modelling techniques, to produce reliable design models which minimise the occurrence of stable obstructions and provide reliable methods for increasing fine powder flow rates.
