About this event

This evening lecture is jointly organised by CIWEM and supported by ICE Wales Cymru.

Presentation overviews

Are energetic tidal straits suitable for power generation? – Dr Paul Evans, Intertek
Many coastal areas around the UK are configured such that tidal currents are accelerated by headlands and islands making them attractive tidal energy sites. This presentation focuses on tidal velocity data measured in Ramsey Sound in Pembrokeshire, a macrotidal strait that accommodates circulation from the Irish Sea with peak spring tide velocities exceeding 3 ms-1, and an area that is soon to become Wales' first TST demonstration site.

Computational modelling of tidal range projects along the Welsh coastline – Dr Athanasios Angeloudis, Cardiff University
This study draws attention to the opportunities and the challenges associated with tidal range schemes. These large scale projects aim to harness the renewable energy facilitated by the substantial tidal range reported in certain parts of the UK and especially along the Welsh coastline and in the Severn estuary.

Hydro-environmental modelling of the Severn Barrage – Sam Bray, Cardiff University
The Severn Barrage has been a widely researched and discussed topic in recent years, due to its enormous energy generating potential and environmental implications. The presentation will focus on recent modelling improvements, including enhancements made to the numerical representation of turbines and sluices.

Please contact Tracey Dunford to confirm your attendance via welsh@ciwem.org

Light refreshments will be served from 5.30pm to 6.00pm. The presentations will start at 6.00pm and there will be opportunities to ask questions throughout the evening. Places at this event are free but limited and booking is essential.

Dr Paul Evans – Intertek

Paul Evans is employed as a Consultant in the Modelling, GIS and Metocean team at Intertek's Energy & Water Consultancy Services (formerly Metoc) group where he is currently developing a coastal model to assess a variety of water quality issues. Paul is also a Visiting Lecturer at Cardiff University's School of Earth and Ocean Sciences focusing on Observational Physical Oceanography and Coastal Hydrography with an emphasis on Marine Renewables. Paul has recently finished a four-year fixed-term contract initially within the School of Earth and Ocean Sciences as a Research Assistant for the Low Carbon Research Institute Marine Convergence programme and later at the School of Engineering as a Research Associate focusing on the feasibility of power extraction from a novel tidal energy scheme through Computational Fluid Dynamics (CFD) modelling. Paul has also completed a PhD in tidal hydrodynamics within the School of Earth and Ocean Sciences. Paul has an MSc in coastal engineering from the University of Plymouth and a BSc in marine geography from Cardiff University.

Dr Athanasios Angeloudis – Cardiff University’s Hydro-environmental Research Centre

Athanasios Angeloudis graduated with a civil engineering MEng (Hons) degree in 2010 from Cardiff University, prior to joining the Hydro-environmental Research Centre as a research student. Upon completion of his PhD in 2014, he continued as a Research Associate as part of an Atlantic Area transnational project on marine renewable energy. His main areas of interest are environmental hydraulics, tidal energy, water treatment, computational fluid dynamics and physical modelling.

Sam Bray – Cardiff University’s Hydro-environmental Research Centre

Sam Bray is currently in the closing stages of a PhD at Cardiff University, focusing on the hydro-environmental modelling of marine renewable energy devices, with particular application to the Severn Barrage. This study is funded by HPC-Wales and Fujitsu, allowing the use of the supercomputing network to aid with large-scale simulation of potential marine renewable schemes. Prior to the PhD, Sam completed a civil and environmental engineering undergraduate degree, also at Cardiff University. Sam hopes to follow the PhD with a career in which he can apply his expertise and enthusiasm for tidal range renewable projects.
