Dissecting non-equilibrium effects in wall turbulence

该项目旨在促进对非平衡条件下壁面湍流的理解。重点是粗糙表面上的湍流，其中大块流动沿着表面的流向长度减速。这种流动在重要的实际应用中经常遇到，例如飞机机翼后缘或流动扩散器内部，这些在工业中无处不在。新的实验和数值模拟将提供明确的数据，以揭示这些流动的尺度规律，从而实现可靠的预测。

This project aims to progress understanding of wall-bounded turbulent flows under non-equilibrium conditions. The focus is on turbulent flows over rough surfaces where the bulk flow decelerates along the streamwise length of the surface. Such flows are regularly encountered in important practical applications, such as over the trailing edge of an airplane wing or inside a flow diffuser, which are ubiquitous in industry. Novel experiments and numerical simulations will provide the definitive data needed in order to uncover the scaling laws of these flows, thus enabling their reliable prediction.
