Predicting and controlling turbulent fluid flow next to a solid surface (the turbulent boundary layer) is of critical importance to ensuring a sustainable energy and environmental future. While recent research has yielded a clearer physical understanding of these flows, converting this understanding into tools useful to engineering practice remains a central obstacle. The proposed research directly addresses this fundamental challenge by precisely connecting the eddy interactions of the turbulence to the mathematical equations that rigorously describe these flows. As such it holds breakthrough potential toward the development of turbulent boundary layer prediction and control schemes that do not rely on ad hoc models or assumptions.

预测和控制固体表面(湍流边界层)附近的湍流流动对于确保可持续的能源和环境未来至关重要。虽然最近的研究对这些流动有了更清晰的物理理解，但将这种理解转化为对工程实践有用的工具仍然是一个主要障碍。这项拟议的研究通过精确地将湍流的涡流相互作用与严格描述这些流动的数学方程联系起来，直接解决了这一根本挑战。因此，它在发展不依赖特别模型或假设的湍流边界层预测和控制方案方面具有突破性的潜力。
