The proposed research program concerns the development and application of models for permeable porous materials using Computational Fluid Dynamics (CFD). Porous materials exist in almost everything around us, from bone and tissue, to clothing and foods, to soils and minerals, and materials of all kinds, whether naturally occurring or manufactured. As such, our understanding of processes like water and air filtration, energy and moisture exchange, and our ability to utilize the unique properties of porous materials to develop devices like fuel cells, heat pipes and highly-efficient energy capture/recovery devices relies on our understanding of how these porous materials function under different conditions and in different environments. CFD is a continually emerging and growing technology that has seen widespread application in industrial, environmental and physiological domains. The proposed research program describes initiatives that will extend the capability of current CFD porous media modeling tools to include: the effects of pore-structure on the treatment of interfaces; pore-structure/wall effects on convective heat transfer, momentum and dispersion; the impact of pore-structure on the effective absorption of incident radiation, and mass/chemical exchange. These initiatives are critical building blocks for the longer-term goals of exploring and developing new applications in: solar and geophysical energy capture, and energy recovery and exchange in HVAC and food storage. The projects proposed in this research program target the development of specific computational capabilities that will enable exploration of physical processes and development of new technologies, thus extending the boundaries of CFD application while providing an excellent training environment for graduate research students at all levels.

拟议的研究计划涉及使用计算流体动力学（CFD）的可渗透多孔材料模型的开发和应用。 多孔材料几乎存在于我们周围的一切，从骨骼和组织，到衣服和食物，到土壤和矿物质，以及各种材料，无论是天然存在的还是人工制造的。因此，我们对水和空气过滤、能量和水分交换等过程的理解，以及我们利用多孔材料的独特性能开发燃料电池、热管和高效能量捕获/回收设备等设备的能力，都依赖于我们对这些多孔材料在不同条件和不同环境下如何发挥作用的理解。CFD是一种不断发展的新兴技术，在工业、环境和生理领域得到了广泛的应用。 拟议的研究计划描述的举措，将扩展当前的CFD多孔介质建模工具的能力，包括：孔隙结构的界面处理的影响;对流传热，动量和分散的孔隙结构/壁的影响;入射辐射的有效吸收的影响，和质量/化学交换。这些举措是探索和开发新应用的长期目标的关键组成部分：太阳能和地球物理能量捕获，以及暖通空调和食品储存中的能量回收和交换。本研究计划中提出的项目旨在开发特定的计算能力，从而能够探索物理过程和开发新技术，从而扩展CFD应用的边界，同时为各级研究生提供良好的培训环境。
