Abstract: As part of the FLOWBEC project, a CFD model of Marine Current Turbine's SeaGen turbine was developed to simulate downstream wake effects caused by both the turbine rotors and the structure. This model demonstrates the highly transient, three-dimensional nature of the flow behind a tidal turbine, and indicates that the wakes behind commercial-scale turbines may persist for many hundreds of metres downstream.

Bio: Angus spent several years at Heriot-Watt modelling wind farms, before becoming a research fellow at IES in 2012. He uses high-resolution CFD models to analyse the turbulent flow around tidal turbines, and understand their interaction with the environment. He is currently developing a tidal model of the Sound of Islay to investigate the large turbulent flow structures that often occur at energetic tidal sites.

Speaker 2: Zhi Yung Tay.

Abstract: Very Large Floating Structure (VLFS) has gained great interest in land scarce countries such as Singapore, Japan and the Netherlands. It provides an alternative to land reclamation in order to create land parcels for development. In the process of designing the VLFS, the elastic response of the structure under wave action has to be investigated. Such response due to its flexible nature is known as the hydroelastic response. In this seminar, Dr. Zhi Yung Tay will be presenting his research and industrial works related to the hydroelastic response of the VLFS projects carried out in Singapore. He will also highlight on the potential of VLFS technology for various application.

Bio: Dr. Zhi Yung Tay is currently an IES postdoctoral research associate working on the EcoWatt2050 Project in investigating the hydrodynamic effects of large scale arrays of marine energy devices in the context of climate change. Prior to joining IES as a PDRA, he was a senior research engineer in Keppel Offshore and Marine Technology Centre, Singapore and a research fellow in the Engineering Science Programme, National University of Singapore (NUS). He holds a PhD in Engineering from NUS and specialises in the area of fluid-structure interaction, computational engineering and has vast experience in the design of various floating structures.
