Impact of spatially uniform and irregular rough surfaces on drag reduction

本计画旨在了解流体在空间均匀及不规则粗糙壁面上之紊流输送机制。它将提供不规则粗糙度的精确建模和高保真度模拟。预期的结果是物理理解的湍流现象，在这些流量，和新颖的不规则粗糙壁流的流量控制，导致显着的阻力减少在澳大利亚的运输行业。其益处与涉及粗糙壁的工程应用和环境应用相关，从而能够更好地预测颗粒物质分散

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
