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 ...

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 ...

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 ...

Tower fairings are a promising method to reduce wake for down wind turbines, with the drawback that the performance may be lost at high angles of attack. For example, the E863 airfoil has a much smaller wake than a cylinder ...

We will present novel modifications of the three-equation k-kL-ω eddy viscosity model proposed by Walters and Cokljat [1] for the adverse pressure gradient flows that occur on wind turbine blades and airfoils. The original ...

Now that wind-farms are becoming increasingly larger, the economics and physics of wind farms become intrinsically coupled and important when designing large wind farms. It is important to develop wind farm models in which ...

The underwater sound levels generated by offshore wind turbine farms is a concern because of the possible environmental impact on marine mammals. This paper will consider how sound generated by a wind turbine is transmitted ...
