3. Wind-turbine aerodynamics - Wikipedia

   en.wikipedia.org/wiki/Wind-turbine_aerodynamics

   Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.

4. Tip-speed ratio - Wikipedia

   en.wikipedia.org/wiki/Tip-speed_ratio

   The tip-speed ratio, λ, or TSR for wind turbines is the ratio between the tangential speed of the tip of a blade and the actual speed of the wind, v. The tip-speed ratio is related to efficiency, with the optimum varying with blade design. [1] Higher tip speeds result in higher noise levels and require stronger blades due to larger centrifugal ...

5. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   Different materials have varying effects on the efficiency of wind turbines. In an Ege University experiment, three wind turbines, each with three blades with a diameter of one meter, were constructed with blades made of different materials: A glass and glass/carbon epoxy, glass/carbon, and glass/polyester. When tested, the results showed that ...

6. Darrieus wind turbine - Wikipedia

   en.wikipedia.org/wiki/Darrieus_wind_turbine

   There are several closely related wind turbines that use straight blades. This design of the turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer; filing for the patent was October 1, 1926. There are major difficulties in protecting the Darrieus turbine from extreme wind conditions and in making it self-starting.

7. Diffuser-augmented wind turbine - Wikipedia

   en.wikipedia.org/.../Diffuser-augmented_wind_turbine

   Traditional open turbine designs are also limited by Betz's law, which states that for a bare turbine in open wind, no more than 16/27 of the total wind kinetic energy can be converted to electrical energy. [4] 59% is not the most efficient rate, so several designs have been made in order to get around this limitation. Designs include the ...

   Vineyard Wind's turbine AW-38 at the far south west section of the offshore wind farm, 22 miles south of Martha's Vineyard. One of the turbine's blades failed last month, splintering into pieces ...

9. Blade element momentum theory - Wikipedia

   en.wikipedia.org/wiki/Blade_Element_Momentum_Theory

   Whereas the streamtube area is reduced by a propeller, it is expanded by a wind turbine. For either application, a highly simplified but useful approximation is the Rankine–Froude "momentum" or "actuator disk" model (1865, [1] 1889 [2]). This article explains the application of the "Betz limit" to the efficiency of a ground-based wind turbine.
