Within the UK, the highest GHG emitting sectors are the energy supply and transportation sectors, which account for 49% of total emissions or 21.9% and 27.1% respectively. The tidal energy is one of the reliable renewable sources, but the technology still within its infancy stages of development and deployment, the cost per unit of energy is higher than other renewable technologies.<\/p>\n<p>This study is to model the performance of a bi-directional ducted tidal stream turbine, operating near the surface, in an attempt to increase the power generated by the turbine. Model simulations include the effects of different camber profiles, internal and external wall shapes and the addition of open and closed centre turbines, as well as surface waves at different positions throughout the water column. This research is expected to contribute to the EPSRC\u2019s decarbonation agenda.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Project: Analysis of Near-Surface Bidirectional Ducted Tidal Stream Turbines Over the last few decades the current impacts and future consequences of emitting large quantities of greenhouse gases (GHGs) has been recognised as an important phenomenon that needs to be addressed, on both a public and governmental level, in order to reduce the economic and health<\/p>\n","protected":false},"author":1083,"featured_media":0,"parent":9,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1634","page","type-page","status-publish","hentry"],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/P6QOqN-qm","jetpack-related-posts":[{"id":741,"url":"http:\/\/sites.cardiff.ac.uk\/coastal\/projects\/lcri-marine\/","url_meta":{"origin":1634,"position":0},"title":"LCRI-Marine","author":"CoastalRes@Cardiff","date":"10\/10\/2015","format":false,"excerpt":"Low Carbon Research Institute (LCRI) Marine This project is funded by WEFO with EU convergence funds.
