Impact of roughness on adverse pressure gradient turbulent boundary layers

本项目旨在开发一种测量高速流动中时间分辨流体速度矢量场的新技术，以前所未有的细节研究逆压梯度环境下的粗糙壁湍流。通过使用这种创新的工具来研究发电和运输中广泛存在但知之甚少的湍流，该项目寻求产生新的知识。预期的成果包括开发新的仪器和基础知识，从而改进设计，提高发电和运输的效率，从而提高能源安全性，减少温室气体排放，提高个人和社会的生活质量。

This project aims to develop a novel technique for measuring time-resolved fluid velocity vector fields in high-speed flows to investigate rough wall turbulence in adverse pressure gradient environments in unprecedented detail. By using this innovative instrument to study these widespread but poorly understood turbulent flows in power generation and transport, the project seeks to generate new knowledge. Expected outcomes include the development of a new instrument and fundamental knowledge leading to improved designs with higher efficiencies in power generation and transport, resulting in significant benefits such as increased energy security, reduced greenhouse gas emissions, and improved quality of life for individuals and society.
