Transition to turbulence in the wake of a circular cylinder

本项目旨在研究稳定流作用下圆柱尾迹从层流到湍流的流动转变。该项目期望通过先进的数值模拟产生关于复杂流动行为和流动过渡到湍流的物理机制的新知识。预期的结果包括对流动演变为湍流的物理理解，以及对层流和湍流特征的理解，以及在流动控制背景下对湍流的抑制。所产生的知识将适用于海上石油和天然气工业以及新兴的海上可再生能源工业中使用的海底传输和通信电缆的改进设计和安全操作。

This project aims to investigate the flow transition from laminar to turbulent in the wake of a circular cylinder subjected to steady current. The project expects to generate new knowledge on the complicated flow behaviours and physical mechanisms for flow transition to turbulence through advanced numerical modelling. Expected outcomes include a physical understanding of the flow evolution to turbulence, as well as an understanding of the laminar and turbulent flow characteristics and the suppression of turbulence in the context of flow control. The knowledge generated will be applicable to improved design and safe operations of the sub-sea transmission and communication cables used in the offshore oil and gas industry and the emerging offshore renewable energy industry.
