Turbulent inflow characteristics for hydrokinetic energy conversion in rivers

Neary, V.S.; Gunawan, B.; Sale, D.C. - In: Renewable and Sustainable Energy Reviews 26 (2013) C, pp. 437-445

Marine and hydrokinetic technologies, which convert kinetic energy from currents in open-channel flows to electricity, require inflow characteristics (e.g. mean velocity and turbulence intensity profiles) for their siting, design, and evaluation. The present study reviews mean velocity and...

The extractable power from a split tidal channel: An equivalent circuit analysis

Cummins, Patrick F. - In: Renewable Energy 50 (2013) C, pp. 395-401

Considerable interest exists in the possibility of exploiting strong tidal currents as a source of renewable energy. Methods to understand and evaluate this resource have been developed for simple flow configurations, such as a tidal channel linking the open ocean to an inner basin. More...

Assessing the potential of urban wind energy in a major UK city using an analytical model

Millward-Hopkins, J.T.; Tomlin, A.S.; Ma, L.; Ingham, D.B. - In: Renewable Energy 60 (2013) C, pp. 701-710

An analytical methodology for predicting above-roof mean wind speeds in urban areas is first used to map wind speeds over four different UK cities. The methodology utilises detailed geometric data describing buildings and vegetation to calculate the aerodynamic characteristics of the urban...

A wave energy resource assessment case study: Review, analysis and lessons learnt

Smith, Helen C.M.; Haverson, David; Smith, George H. - In: Renewable Energy 60 (2013) C, pp. 510-521

A case study of the development of an overall resource assessment for the Wave Hub site in the southwest UK is … presented. Wave Hub is one of the earliest large-scale wave farms planned. Several resource assessment studies have been …-term global model datasets shows notable inter-annual variability. It is thus concluded that a resource assessment methodology …

Estimation of the wave power resource in the Caribbean Sea in areas with scarce instrumentation. Case study: Isla Fuerte, Colombia

Ortega, Santiago; Osorio, Andres F.; Agudelo, Pablo - In: Renewable Energy 57 (2013) C, pp. 240-248

There are great difficulties in properly evaluating the power present in waves in the Caribbean Sea due to of the scarcity of marine instrumentation and the reduced length of the existing records. This research aimed to design a new methodology for estimating wave power potential in places...

Mapping the wind resource over UK cities

Millward-Hopkins, J.T.; Tomlin, A.S.; Ma, L.; Ingham, D.B. - In: Renewable Energy 55 (2013) C, pp. 202-211

Decentralised energy sources, such as small-scale-wind energy, have a number of well-known advantages. However, within urban areas, the potential for energy generation from the wind is not currently fully utilised. One of the most significant reasons for this is that the complexity of air flows...

Exceeding the Betz limit with tidal turbines

Vennell, Ross - In: Renewable Energy 55 (2013) C, pp. 277-285

The Betz limit sets a theoretical upper limit for the power production by turbines expressed as a maximum power coefficient of 16/27. While power production by wind turbines falls short of the Betz limit, tidal turbines in a channel can theoretically have a power coefficient several times larger...

Evaluation of a semi-empirical model for predicting the wind energy resource relevant to small-scale wind turbines

Weekes, S.M.; Tomlin, A.S. - In: Renewable Energy 50 (2013) C, pp. 280-288

An existing semi-empirical model for estimating the wind energy resource relevant to small-scale wind turbines has been investigated by comparing its predictions to wind speed data collected from 38 UK sites located in a variety of terrains. A range of error metrics have been used to judge the...
