  • Methods and systems for comparing vertical axis turbine arrays and providing configurations thereof
    Patent number: 9399981
    Abstract: A method for providing potential flow elements including a vortex to capture rotation of a turbine, a dipole to capture a blockage effect of the turbine, a sink to capture extracted energy from wind by the turbine, and a source to capture recovery of flow due to inflow from around the turbine is described. Methods for providing configurations of a VAWT array based on a desired attribute of the array, using a low-order model when the array is subject to physical constraints are also described.
    Type: Grant
    Filed: December 18, 2014
    Date of Patent: July 26, 2016
    Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Anna Craig, John Oluseun Dabiri
  • V-shaped arrangements of turbines
    Patent number: 9175669
    Abstract: A V-shaped arrangement of turbines adapted to orient in such a manner that crosswind enters the arrangement in a direction that is substantially parallel to the axis bisecting the arrangement is described. The V-shaped arrangement includes clockwise rotating turbines and counterclockwise rotating turbines.
