Geometry of wall-turbulence and its potential to advance scalable models

该项目旨在揭示壁面湍流的统计几何与其瞬时运动的动力学相互作用之间的联系。预测相对运动表面上湍流流动的复杂行为，对于气候和农业的大气建模以及减少化石燃料使用对环境的影响至关重要。壁面湍流统计是根据可预测的几何结构来组织的，而众所周知的壁面湍流动力学的复杂性可以通过其固有的几何来澄清。本项目旨在为工程和大气壁流预测奠定基础，从而增强大气流动预测，降低能源消耗，进一步提高环境可持续性。

This project aims to unravel the connections between the statistical geometry of wall-turbulence and the dynamical interactions of its instantaneous motions. Predicting the complex behaviour of turbulent fluid flow over surfaces in relative motion is central to atmospheric modelling for climate and agriculture, and reducing the environmental effect of fossil fuel usage. Wall-turbulence statistics organise according to a predictable geometric structure, and the notorious complexity of turbulent wall-flow dynamics could be clarified through its inherent geometry. This project expects to construct a basis for predicting engineering and atmospheric wall-flows, which would enhance atmospheric flow prediction, reduce energy consumption and further environmental sustainability.
