Model studies of the flow and thermal behaviour of non-spherical particles in fluid bed reactors

澳大利亚钢铁业的营业额约为110亿澳元（占总制造业的5%），是澳大利亚最大的制造业。铁矿石烧结和高炉炼铁是钢铁联合企业的两个重要工序。该项目旨在了解和模拟这两个过程中非球形颗粒的颗粒-流体流动和热行为，制定改善过程控制和生产率以及节能的策略。本文的研究成果（理论/模型/认识）对在矿物/冶金/化学工业中广泛应用的流化床反应器有一定的参考价值。它们的应用可以提高澳大利亚钢铁和其他行业的竞争力。

The Australian steel industry has a turnover of around $11 billion (5% of total manufacturing), being a largest manufacturing sector in Australia. Iron ore sintering and blast furnace ironmaking are two important processes in an integrated steel works. This project aims to understand and model the particle-fluid flow and thermal behaviour of non-spherical particles in the two processes, formulating strategies for improving the process control and productivity and energy saving. The research outcomes (theory/model/understanding) are useful to fluid bed reactors which are widely used in mineral/metallurgical/chemical industries. Their application can improve the competitiveness of the steel and other industries in Australia.
