Turbulent fluid flows near solid surfaces are present in many areas of everyday life: from the drag experienced on air, sea and road vehicles, to governing the mixing processes in combustion chambers, and in the transport of pollutants and particulates in our cities and towns. Unfortunately our understanding of these complex flows is limited, and hence so to is our ability to model or control them. This project addresses this problem with the goal of providing new physical insights and models that can be used for efficient and accurate numerical simulations. The simulations will not only compute the average statistics but also the time-varying properties, which are crucial in many engineering and environmental processes.

固体表面附近的湍流流动存在于日常生活的许多领域：从空中、海上和道路车辆所经历的阻力，到控制燃烧室中的混合过程，以及我们城市和城镇中的污染物和颗粒物的运输。不幸的是，我们对这些复杂流动的理解是有限的，因此我们建模或控制它们的能力也是有限的。这个项目解决了这个问题，目的是提供新的物理见解和模型，可以用于高效和准确的数值模拟。模拟不仅会计算平均统计量，还会计算时变特性，这在许多工程和环境过程中是至关重要的。
