Modelling of particle-fluid reactive flows coupled with phase changes

本计画旨在发展一个完整的数学模型，以可靠地描述多相反应流与相变化的耦合。在许多能源密集型工业中广泛遇到具有相变的颗粒-流体反应流动，然而由于缺乏对特别是多相流动、相变及其相互作用的复杂现象的理解，过程设计和优化受到阻碍。 该模型将通过结合先进的粒子尺度数值技术和基于预数据库的热力学模型，并通过物理实验来支持。这些成果将应用于对澳大利亚经济和技术未来至关重要的一系列行业。这将有助于改变澳大利亚的火法冶金和化学工业，为低品位煤和铁/铜矿石等一系列澳大利亚矿产开辟新市场，并最终提高澳大利亚经济的竞争力。

This project aims to develop an integrated mathematical model for reliably describing multiphase reactive flow coupled with phase change. Particle-fluid reactive flows with phase changes are widely encountered in many energy-intensive industries, yet process design and optimization are hindered by the lack of understanding of complex phenomena governing particularly multiphase flow, phase change and their interactions. The model will be achieved by means of combining advanced particle-scale numerical techniques with pre-database-based thermodynamic model, supported by physical experiments. The outcomes will be applied across a range of industries of vital importance to Australian economic and technological future. It will help transform Australian pyrometallurgy and chemical industries, open new markets for a range of Australian minerals like low-grade coal and iron/copper ore, and ultimately enhance competitiveness of Australian economy.
