This Research Training project involves two postdoctoral fellows for three years, 3 graduate students for 4 years and 10 undergraduates for 5 years which will perform research in experimental and theoretical fluid dynamics occurring in and around the University of North Carolina Joint Fluids Laboratory. Specifically, the research and training will be focused upon the complicated interaction between solid bodies and fluids arising in a variety of biologically and environmentally relevant scenarios including systems with strong and sharp density stratification such as occurring in the oceans and atmosphere as well as in highly viscous systems relevant to microbiology. The effort brings together new experimental phenomena with quantified mathematical modeling.Fluid dynamics is central to understanding the behavior of many physical systems on a wide range of length and time scales spanning our atmosphere and oceans down to the smallest swimming micro-organisms. In particular, understanding how a body moves fluid and in turn how the fluid can impact a body is fundamental to understanding how our environment works, which is necessary to even begin to assess human impacts on climate. Our the large scales, the oceans and atmospheres are complicated fluid systems possessing strong density variations, and the associated phenomena are complex and central to building a more quantified understanding of climate. On smaller scales, biological systems are bathed in fluids with varying viscosities which are moved via the motion of small hair-like structures called cilia. Developing quantified analytical and computational models to predict these dynamics has implications for improved understanding of lung function and disease such as Cystic Fibrosis. This research training grant is dedicated towards improved experimental and theoretical understanding of the interaction between solid bodies and complicated fluid systems.

该研究培训项目涉及三年的两名博士后研究员，3名研究生4年和10个本科生，共5年，这将在北卡罗来纳大学联合流体实验室及其周围发生的实验和理论流体动力学研究中进行研究。 具体而言，研究和培训将集中在固体和液体之间的复杂相互作用上与微生物学有关的系统。 努力通过量化的数学建模将新的实验现象融合在一起。流体动力学对于理解许多物理系统的行为至关重要，这是许多物理系统在跨越我们的大气和海洋的范围范围和时间尺度上，直至最小的游泳微生物。 特别是，了解人体如何移动液体，而液体如何影响人体对于理解我们的环境的工作方式至关重要，这甚至是开始评估人类对气候的影响所必需的。 我们的大尺度，海洋和大气是具有强密度变化的复杂流体系统，相关现象是复杂的，并且是建立对气候更量化的理解的核心。 在较小的尺度上，生物系统被沐浴在具有不同粘度的液体中，这些粘度通过称为纤毛的小型头发样结构的运动移动。 开发量化的分析和计算模型来预测这些动力学，对改善对肺功能和疾病（例如囊性纤维化）的了解具有意义。 该研究培训赠款专门用于改善对固体与复杂流体系统之间相互作用的实验和理论理解。
