This project aims to investigate the flow around a circular cylinder, placed near a plane boundary, as a fundamental fluid phenomenon and for applications of designing subsea pipelines. The proposed work will be carried out using a combined approach of physical model testing and numerical study. The effect of the plane boundary on flow transition from 2D to 3D, from sub-critical to critical turbulence regime will be examined. The project aims to derive a comprehensive set of force coefficients to predict hydrodynamic forces on pipelines that will improve the design of subsea pipelines. This project could provide significant benefits for the Australian subsea oil and gas industry.

本项目旨在研究作为基本流体现象的平面边界附近圆柱体周围的流动，并用于设计海底管道。建议的工作将采用物理模型试验和数值研究相结合的方法进行。将检查平面边界对从2D到3D、从亚临界到临界湍流状态的流动转变的影响。该项目旨在推导出一套全面的力系数，以预测管道上的水动力，从而改进海底管道的设计。该项目可为澳大利亚海底石油和天然气工业带来重大利益。
