Experimental and Analytical Investigations of Flows in Porous Media

小行星9307197 对多孔介质中的自然对流进行了大量的实验研究，并辅以数值模拟。 这项研究的主要目的是进一步探索和利用一种新的非侵入性诊断技术，称为改良阴影技术（MST）。 特殊排列的多孔材料可以使光信号在没有折射衰减的情况下进入。 然后，这种技术可以可视化对流模式。 意外的流动模式，在这样的媒体将进一步调查，并探讨该技术的实用性的二元混合物。 除了进一步开发这一新工具，以产生更多和更好的洞察多孔介质流动，调查也是相关的大规模流动模式的敏感性材料微观结构的重要现象。 适用于各种环境和工程系统。 ***

9307197 Behringer A largely experimental investigation is to be carried out of natural convection in porous media, complemented by numerical simulations. The main thrust of the research is to further explore and exploit a novel non-invasive diagnostic technique called the Modified Shadowgraph Technique (MST). Specially arranged porous materials can be made to admit optical signals without refractive attenuation. This technique can then visualize convective patterns. Unexpected flow patterns in such media are to be further investigated, and the utility of the technique for binary mixtures will be explored. Beyond further developing this new tool for generating more and better insight into porous media flow, the investigation is also relevant to the important phenomenon of large scale flow pattern sensitivity to material microstructure. Application is to variety of environmental and engineering systems. ***
