New aspects is added to the wind farm layout optimization problem. A variable hub height non-identical turbines wind farm design is presented. The manufacturers' technical data for 61 commercial horizontal axis wind turbine ...

This talk presents a cost-benefit analysis of three main fuels for electricity generation, namely coal, natural gas, and wind. This analysis incorporates social costs and benefits along with traditionally utilized private ...

A leading obstacle hindering the development of wind turbines to extreme scale is the structural integrity of the blades. Downwind rotors have been shown to give structural advantages for larger systems. However, there is ...

A crucial element in the use of wind as a source of energy in the built environment, is finding ways to maximize its flow. As flow approaches the windward façade of a building's structure, it accelerates causing an increase ...

A new turbulence model, MW, is developed for use in the computational flow over an urban landscape. It addresses the stagnation-point anomaly found in simulations over buildings with the standard k-ϵ and negates the ...

The Department of Energy is leading a second Wind Forecast Improvement Project (WFIP2), which will aim to improve modeling of complex flow. The National Oceanic and Atmospheric Administration (NOAA) will collaborate with ...

A high risk of hurricane is threatening the development of offshore wind energy in the east coast of the United States. Hurricane loads on an offshore wind turbine, namely wind and waves, not only exert large demands but ...

Trailing edge noise remains a primary limiting factor in the widespread implementation of wind turbines, particularly near populated areas. Noise regulations commonly require acoustic de-rating of existing turbines, leading ...

Wind turbine icing represents the most significant threat to the integrity of wind turbines in cold weather. Ice accretion on turbine blades would decrease power production of the wind turbines significantly. Ice accretion ...
