1241349ChristensenThis grant will be used to purchase index-matching fluid to operate an existing large-scale flow facility to explore flows over complex topography (relevant to aerodynamics and geophysical phenomena), within complex geometries (flow in porous media and coral reefs, turbines, etc.) and in the presence of particulates (sediment transport, nutrient transport, pollutant and aerosol dispersion, etc.). The RI-matched (RIM) flow facility will permit Illinois researchers to render complex acrylic solid models and/or particulates optically transparent when immersed in a sodium iodide solution at ~63% by weight, thereby minimizing reflections and distortion and facilitating thorough non-intrusive experimentation. Intellectual Merit - The uniqueness of this facility lies in its large size (0.45 m x 0.45 m x 2.5 m test section), allowing flow studies at relevant scales and Reynolds numbers. This funding from NSF overcomes the remainder of the funding shortfall. Doing so will prevent the team from having to pursue volume reduction that would undermine the novelty and paradigm-shifting capabilities of the large-scale facility as intended with the original MRI funding. Broader Impacts - Researchers on multiple levels (46 undergraduate and 812 graduate students, 35 postdocs and 35 visiting researchers per year anticipated amongst the research groups of the Illinois faculty on the MRI proposal) will immediately benefit from one-of-a-kind training and research experiences once the facility is operational. In particular, this unique training and education will position these researchers as the next generation of leaders in experimental fluid mechanics in both academia and industry. The facility will be run in a shared-use manner, meaning its positive impact will extend well beyond Illinois to researchers at other universities and in the private sector (in addition to the numbers listed above).

1241349Christensen这笔赠款将用于购买指数匹配流体来操作现有的大型流动设施，以探索复杂地形（与空气动力学和地球物理现象相关）、复杂几何形状（多孔介质和珊瑚礁、涡轮机等中的流动）上的流动.) 并存在颗粒物（沉积物输送、营养物输送、污染物和气溶胶扩散等）。 RI 匹配 (RIM) 流动设施将允许伊利诺伊州的研究人员在浸入约 63% 重量的碘化钠溶液中时，使复杂的丙烯酸固体模型和/或颗粒呈现光学透明，从而最大限度地减少反射和扭曲，并促进彻底的非侵入性实验。智力优势 - 该设施的独特之处在于其大尺寸（0.45 m x 0.45 m x 2.5 m 测试部分），允许在相关尺度和雷诺数下进行流动研究。 NSF 的这笔资金弥补了剩余的资金缺口。这样做将防止团队不得不追求体积减小，从而破坏大型设施的新颖性和范式转换能力，而这正是原始 MRI 资金的预期目的。更广泛的影响 - 多个级别的研究人员（预计伊利诺伊大学 MRI 提案的研究小组中每年有 46 名本科生和 812 名研究生、35 名博士后和 35 名访问研究人员）将立即受益于独一无二的培训和设施投入运营后的研究经验。特别是，这种独特的培训和教育将使这些研究人员成为学术界和工业界实验流体力学的下一代领导者。该设施将以共享使用的方式运营，这意味着其积极影响将远远超出伊利诺伊州，影响到其他大学和私营部门的研究人员（除了上面列出的数字之外）。
