Wall turbulence control: beyond the canonical smooth wall case

该项目旨在通过研究粗糙壁湍流边界层如何响应壁面抽吸和吹扫等变化来填补壁湍流领域的关键知识空白。移动车辆表面粗糙化所造成的经济和环境成本在运输行业（公路，铁路，航空和海运）以及最终在澳大利亚都是惊人的。该项目将产生新的知识，以确定是否可以控制或管理粗糙表面上的湍流，以实现诸如减少粗糙化海崖体阻力的结果，例如船体因污垢而粗糙化的船舶。该项目预计将提高对壁湍流控制的理解，并将带来显著的好处，如改进的控制技术和更好的预测和描述壁湍流。

This project aims to fill a critical knowledge gap in the area of wall turbulence by investigating how a rough wall turbulent boundary layer responds to changes, such as wall suction and blowing. The economic and environmental costs caused by the roughening of surfaces on moving vehicles is staggering in the transport industry (roads, rails, air and sea) and ultimately for Australia. This project will generate new knowledge to ascertain whether or not turbulent flows over rough surfaces can be controlled or managed to achieve outcomes such as reducing the drag of a roughened bluff body, for example a ship whose hull is roughened by fouling. The project expects to improve understanding of wall turbulence control, and will lead to significant benefits such as improved control technologies and better prediction and description of wall turbulence.
