Multiscale modelling of fluid–particle transport in porous media

其目的是使用多尺度方法来严格模拟多孔介质中的流体-颗粒输运-这是许多工程问题中的基本过程。利用先进的并行计算工具，开发了一个微尺度模型，将相互作用的谷物，水和粒子。该模型和创新的放大方法将改变我们对机制的理解，并允许在稳定和非稳定多孔流中开发颗粒输运的预测模型。基础知识和新一代数值模型将支持技术进步，使铁路和公路建设及其维护、燃料和可再生能源开采、沿海土壤和水保护以及森林火灾控制直接受益。

The aim is to use a multiscale approach to rigorously model fluid–particle transport in porous media – a fundamental process in many engineering problems. With advanced parallel-computing tools, a microscale model is developed to incorporate interacting grains, water, and particles. The model and innovative upscaling methods will transform our understanding of mechanisms, and allow development of predictive models for particle transport in both steady and unsteady porous flows. The fundamental knowledge and new-generation numerical models will support technological advances to directly benefit rail and road construction and their maintenance, fuel and renewable-energy extraction, coastal soil and water protection, and bushfire control.
