The OES poster award at ICOE 2014 

The OES sponsored a €3,000 prize fund to students selected by an international jury for the best posters presented by students at ICOE 2014.

This award at ICOE 2014 on behalf of the Ocean Energy Systems (OES) is intended to identify an early career individual who we expect to continue to make significant contributions in making industrial ocean energy a reality.

Abstract
A versatile numerical model for the simulation of flow past horizontal axis tidal turbines has been developed. Most large-scale models use the shallow water equations and therefore can fail to account for important turbulent physics. The current model is based on actuator disc momentum (ADM) theory, uses a RANS model to account for turbulence and utilises dynamic mesh adaptivity. The same ADM implementation has been carried out in OpenFOAM allowing for a comparison between the two numerical models. Furthermore, a series of laboratory experiments were carried out in the hydrodynamics laboratory of the Civil Engineering Department at Imperial College London which were used to help validate the numerical model. This model has been developed with the aim that it will be coupled with and embedded within larger numerical models simulating tidal flows in realistic domains, e.g. the Inner Sound of the Pentland Firth. This is where the adaptive meshing capability is a major advantage as it enables the mesh to be refined only in the locations required, thus making optimal use of finite computational resources. The resulting capability will be used for resource optimisation and to assess environmental impacts.

CV Description:
PhD student at Imperial College London researching tidal turbine array design, focusing on the Inner Sound of the Pentland Firth. My PhD is in collaboration with MeyGen Ltd who intend to deploy up to 398MW of offshore tidal stream turbines in this site. I'm part of the applied modelling and computation group (AMCG) where we focus on the development and application of innovative modelling techniques for a range of applications including fluid flows and global ocean models. I have an MEng in Engineering from Cambridge University where I specialised in Fluid Mechanics. One of the major advantages of the Engineering course at Cambridge is that every student initially develops a basic knowledge of all the engineering divisions for the first two years of study and this has provided me with a good foundation when faced with real life engineering problems. Prior to starting my PhD, I worked for a year at Camfridge Ltd, a start-up company investigating the use of magnetocaloric material to develop more efficient and environmentally friendly fridge technology.

Abstract
Numerical modeling and scaled physical modeling of the Galway Bay Wave Energy test site were the main outcomes of the research. Proposed infrastructure for the site includes a floating power system to act as a power and data acquisition platform as well as a local grid connection. The modeling done for this research included this floating power system as well as a generic oscillation water column type wave energy converter. Numerical analysis was performed using Ansys Aqwa, and physical modeling testing was performed at 1:25 scale at the National Ocean Energy Test Facility at University College Cork, Ireland. Results of the research include characterizing the expected response of the full scale bodies as well as informing future testing to be done at 1:10 scale. This work will ultimately influence the final implementation of the Galway Bay Wave Energy test site.

CV Description:
Bret is currently in the middle of a two year postdoc funded by the United States Department of Energy (USDOE) Energy Efficiency and Renewable Energy (EERE). The first year of the postdoc was in Cork, Ireland at University College Cork (UCC). The second year is in Corvallis, Oregon USA at Oregon State University working with the Northwest National Marine Renewable Energy Center (NNMREC). Bret graduated with a PhD in Electrical Engineering from Oregon State University in 2013 with a dissertation entitled “On the Design, Modeling, and Testing of Ocean Wave Energy Converters”. Bret also graduated with bachelor and master degrees from California State University, Chico in Electrical Engineering in 2005 and 2008 respectively. His interests are in renewable energy systems generally, with his most recent work in marine renewable energy, specifically numerical and scaled physical model testing of ocean wave energy converters.

Abstract
Wave measurement is of vital importance for assessing the wave power resources and for developing wave energy devices, especially for the wave energy production and the survivability of the wave energy device. Wave buoys are one of the most popular measuring technologies developed and used for long-term wave measurements. In order to figure out whether the wave characteristics can be recorded by using the wave buoys accurately, an experimental study was carried out on the performance of three wave buoy models, viz two Wavescan buoys and one ODAS buoy, in a wave tank using the European FP7 MARINET facilities. This paper presents the test results in both time and frequency domains and the comparison between the wave buoys and wave gauge measurements. The analysis results reveal that for both regular and irregular waves, the Wavescan buoys have better performances than the ODAS buoy in terms of accuracy and the Wavescan buoys measurements have a very good correlation with those from the wave gauges.

CV Description:
With the interests for sustainable development and clear energy, I finished my bachelor major in Hydraulic Engineering in Tsinghua University, July 2011. After that, I started a successive doctoral study focusing on renewable marine energy, especially wave energy. In 2013, I have been worked in Hydraulic & Maritime Research Center (HMRC), University College Cork, Ireland for 6 months as a visiting scholar. My thesis will include the wave energy assessment for some specific area in China, the interaction between the wave and structures, mainly wave buoys, and the hydrodynamic study about the wave buoy arrays through numerical simulations and field tests.
