As shown, the equivalent wind speeds for the 2010 FBCB have actually decreased for most of the state whencompared to the 2007 FBCB wind speeds. This is due to new data and better modeling techniques and represents the best scientific knowledge available.ASCE...
The presented results highlight that the sensitivity of the yearly energy production to geometric uncertainties can be reduced by reducing the rotational speed and increasing the aerodynamic blade loads. 展开 关键词: Design Rotors Wind turbines
In contrast, a multiparty collaboration—in which each party focuses on its strengths and can compensate for other parties’ resource shortcomings—can help companies significantly cut development costs and speed up the overall R&D process. It also enables higher-quality products to be launched faster...
Wind Tunnel Tests Could Help Kites Become a Clean Energy High-Flier The use of kites to capture wind energy and turn it into cost-effective ‘green’ electricity could be coming within reach, with EPSRC-funded research at Imperial College London playing an important role in making it possible....
Then, based on the changes of wind with altitude and gust factor, instantaneous maximum wind speeds were calculated for different return periods at bridge surface height. 展开 关键词: cross-channel project over Qiongzhou strait yearly maximum wind speed data prolongation function of extremeⅠ gust ...
Dynamic Model of Wind Speed Distribution in Wind Farm Considering the Impact of Wind Direction and Interference Effects The accurate and practical wind speed model of wind farm is the basis of the relevant research work of wind power prediction. This paper based on the wind farm and the real-...
wind is always considered to be in parallel and opposite direction to the flight path. In considering helicopter flight, the relative wind can be affected by the rotation of the blades, the horizontal movement of the helicopter, the flapping of the rotor blades, and wind speed and direction. ...
Wind turbine, apparatus used to convert the kinetic energy of wind into electricity. Wind turbines come in several sizes, with small-scale models used for providing electricity to rural homes or cabins and community-scale models used for providing electr
