Simulation and stability of complex three-dimensional flow problems

点击翻译按钮获取中文摘要

High accuracy computational fluid dynamics modelling, together with stability and sensitivity analysis, are key tools in developing deeper and fundamental understanding of complex three-dimensional fluid mechanics problems. The research focus will be on using these techniques to study problems of relevance in the fields of renewable energy and flow-induced vibration. Key problems that will be addressed include three-dimensional wind turbine blade tip flows, including how these flows relate to span-wise flow effects and how tip flows can ultimately be controlled, stability of helical vortex structures in the wakes of wind turbines, and how their break-down can be controlled and modified, and the validity of the independence principle in yawed flow problems including stationary and vibrating cylinder problems.
