四、报告题目：Flow-induced vibrations under free-stream turbulent flows

报告摘要：

The escalating demand for renewable energy technologies has propelled the investigation of galloping and vortex-induced vibration (VIV) to the forefront, seeking to harness eco-friendly energy from natural flow-induced vibration (FIV) phenomena. While limited attention has been devoted to comprehending the influence of free-stream turbulent flow on FIV, especially with respect to the multi-degree-of-freedom fluid-structure interaction systems with cross-flow and in-line responses, low mass-damping ratios, subcritical Reynolds number and variable angle of flow incidence. These will be presented and discussed in this talk based on recent experimental tests which have been carried out in a recirculating water flume at Newcastle University, using a pivoted rigid cylinder with an elastically mounted pendulum and universal joint setup, where repeatable incoming high turbulent flow can be generated and FIV responses can be measured using non-contacting cameras.

主讲人简介：

Dr Narakorn Srinil is presently a Reader in Subsea Engineering at Newcastle University in the UK, internationally recognised for his scientific contribution to the vortex-induced vibration (VIV) research. Dr Srinil and his team (www.staff.ncl.ac.uk/narakorn.srinil/) carry out fundamental, interdisciplinary and applied research in modelling, simulation and experiment of flow-induced vibrations and fluid-structure interactions applicable to offshore, subsea and renewable energy technologies. Presently, Dr Srinil is a co-PI of the EPSRC-funded project “CableDyn: Subsea Power Cable Dynamics Under Complex Ocean Environment” which aims to investigate VIV effects on subsea power cables under waves, currents and turbulence for applications of offshore floating wind turbines, in partnership with Edinburgh (lead PI), Exeter and Southampton Universities.
