Systems and processes involving particulate matter are complex, and due to inadequate understanding and modelling capabilities, rarely reach more than 60% of the design capacity. Given the prominence of these materials in Australia's leading export industries, the potential economic and social impact of this research program is significant. For example, Australia holds the largest known resources of iron ore with annual exports exceeding $3.8 billion; annual wheat exports exceed $3.4 billion and 90% of Australia's sealed roads (granular paved) cost $1 billion per year to maintain. This research will advance knowledge of fundamental behaviour and deliver predictive tools to control and optimise processes involving particulate matter.

涉及颗粒物的系统和过程非常复杂，并且由于理解和建模能力不足，很少能达到设计能力的 60% 以上。鉴于这些材料在澳大利亚主要出口行业中的突出地位，该研究计划的潜在经济和社会影响是巨大的。例如，澳大利亚拥有已知最大的铁矿石资源，年出口额超过38亿美元；每年小麦出口额超过 34 亿美元，澳大利亚 90% 的封闭道路（颗粒铺砌）每年的维护费用为 10 亿美元。这项研究将增进对基本行为的了解，并提供预测工具来控制和优化涉及颗粒物的过程。
