This project aims to improve the prediction of drag where fluid flows over rough surfaces. This is a significant problem, with the uncertainty in drag penalty prediction for shipping alone exceeding ten billion dollars annually. The societal importance of these flows demands action, yet novel approaches must be sought to efficiently explore the wide range of roughness types encountered in practice. An adaptive surface is proposed, where a roughness configuration can be dialled in at the press of a button, to rapidly converge on improved models. A key outcome of this project will be improved predictive models of drag for rough wall flows. Benefits will include improved efficiencies and reduced emissions across a wide range of industries.

该项目旨在改进流体流过粗糙表面时的阻力预测。这是一个重大问题，仅航运业的阻力损失预测的不确定性每年就超过 100 亿美元。这些流动的社会重要性需要采取行动，但必须寻求新的方法来有效地探索实践中遇到的各种粗糙度类型。提出了一种自适应表面，只需按一下按钮即可调入粗糙度配置，以快速收敛到改进的模型。该项目的一个关键成果将是改进粗糙壁流阻力的预测模型。好处将包括提高各行业的效率并减少排放。
