Impact of spatially uniform and irregular rough surfaces on drag reduction

本项目旨在了解流体在空间均匀和不规则粗糙壁面上的湍流输运机制。它将提供不规则粗糙度的精确建模和高保真度模拟。预期的结果是对这些流动中的湍流现象的物理理解，以及对不规则粗糙壁流动的新型流动控制，从而为澳大利亚的运输行业显著减少阻力。这些好处与涉及粗糙墙壁的工程应用和环境应用有关，可以更好地预测颗粒物质的分散

This project aims to understand the turbulent transport mechanism for fluid flow over spatially uniform and irregular rough walls. It will provide accurate modelling of irregular roughness and high fidelity simulations. The intended outcomes are physical understanding of the turbulence phenomenon in these flows, and novel flow control of irregular rough wall flows leading to significant drag reduction for transport industries in Australia. Benefits are relevant to both engineering applications involving rough walls and to environmental applications enabling better prediction of particulate matter dispersion
