  • Savonius wind turbine Wikipedia

    The Savonius turbine is one of the simplest turbines. Aerodynamically, it is a drag-type device, consisting of two or three scoops.Looking down on the rotor from above, a two-scoop machine would look like an "S" shape in cross section.Because of the curvature, the scoops experience less drag when moving against the wind than when moving with the wind.

  • Unconventional wind turbines Wikipedia

    Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2012, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.A second major unit type is the vertical-axis wind turbine (VAWT

  • Vertical axis wind turbine technology continues to improve

    7/08/2017· 1.3.3 A good vertical axis wind mill has to remain stable when it is spinning it. If not, the turbine will “shake its head” when the rotor is turning. That will reduce the turbine’s life and cause other problems such as noise and mechanical wear. So the best solution is to use a coaxial structure for the wind mill and generator. The

  • Possible Dual Rotor Technology for Wind Turbines

    They plan to use the research results to find the best aerodynamic design for a dual-rotor turbine. The goal is to find out where the second rotor should be located, how big it should be, what kind of airfoil it should have, and if it should rotate in the same direction or in the opposite direction.

  • High Performance Foil Rotor Improves De-Ink Pulp Screening

    the existing speed of the OEM rotor (of 16 m/s) was based on the OEM's own optimization work at this mill and the mill's finding that the OEM screen would plug at a rotor tip speed of 15 m/s. Differential pressure (i.e. the feed minus the accept pressure) was monitored as an indication of the stability of the screen. Pulp samples were taken at
