Definitions

  • the present invention relates to the use of foils with vertical axis turbines (VAWT). Although their main use is likely to be with wind, the inventions apply to any kind of fluid flow.
  • VAWT vertical axis turbines
  • Figure 1 is a diagram of a convex foil on a VAWT.
  • Figure 2 is a diagram of the geometric parameters of a VAWT with a foil.
  • Figure 3 is a diagram of fluid flow in Case 15
  • Figure 4 is a diagram of fluid flow in Case 12. DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • VAWT is an abbreviation for Vertical Axis Wind Turbine. It refers here to such a turbine in any flow of fluid. It may be this type even in a horizontal orientation.
  • the term "fluid” refers to gas or liquid, and any reference to fluid refers to both unless otherwise stated.
  • a WDD is a Wind Deflection Device and an FDD is a Flow Deflection Device; they are substantially synonymous with the terms "foil” or “airfoil” as all the above refer to aerodynamic objects that change the flow of a fluid.
  • An FDD or WDD is a broader term because it may refer to partial outline foils that are incomplete. A foil is functionally adjacent to the turbine if it is effective in changing the power output.
  • VAWT foil The principles and operation of a VAWT foil according to the present invention may be better understood with reference to the drawings and the accompanying description.
  • Figure 1 illustrates a VAWT with a stand and shaft (1) and the location of the turbine blades (2).
  • a vertical axis turbine may be made with at least one foil set that is convex to the upstream flow of fluid into the turbine and superior or inferior to the turbine or both as per Figure 1.
  • a lower, convex foil is added in the vicinity of the blades. Said foil may or may not be connected to the turbine's body.
  • the unique additional point is that the foil or foils (3, 5) are convex to the oncoming wind and located above and/or below the blades (2). If an upper foil is present, it may be supported by at least one pole (4).
  • a convex foil forms a ring around the shaft.
  • Figure 2 illustrates the model and parameters used for determining the foil shapes and gives a description of the major parameters.
  • Db is 1.96 meters
  • Hb is 2 meters.
  • Din (7) is the internal diameter of the foil (6 and/or 16).
  • (8) is the chord of the foil at any angle. Note that it may refer to only part of the foil structure.
  • the blades are (9).
  • Sb (10) represents the distance from the foil to the blade.
  • Hb (11) is the height of the blades.
  • Cb (12) is the chord of the blades.
  • Db (13) is the diameter of the blades.
  • Hl (14) is the height of the outer vertical flange (leading edge according to the wind direction) extending from the more traditional foil shape (6 and 16).
  • a substantially vertical flange facing the outside and inferior to the outer edge can be added to increase the velocity of fluid entering the turbine.
  • H2 (15) is the height of the inner flange (trailing edge according to the wind direction) attached to the partial outline foil.
  • the chord is c and it is at an angle of ⁇ . It is emphasized that the deflection "foils” here can contain up to three parts: an outer flange, an intermediate foil, and an inner flange.
  • the models here use a C foil as the intermediate foil shape.
  • the body of the foil is a "C" foil, which was illustrated in a previous patent as a line drawn through the following relative coordinate points in an x ⁇ y axis in any proportional size and any angle of attack, wherein at least one point can vary by an absolute amount of 10% of the chord length: X, Y; 1.732050808, 1; 1.693643087, 0.874364124; 1.646368289, 0.761206475; 1.542617362, 0.546668353; 1.427110653, 0.347651841; 1.29972529, 0.165009761; 1.159575723, 0.000955932; 1.004940323, -0.140607698; 0.824000258, -0.251170312; 0.72335477, -0.288447214; 0.614950141, -0.310804889; 0.497740627, -0.315152056; 0.369386895,
  • the present invention successfully addresses the shortcomings of the presently known configurations by providing a series of optimal foil/vertical axis turbine configurations.
  • a vertical axis turbine comprising: a. a functionally adjacent, externally convex FDD upstream from the turbine.
  • the FDD is inferior (as per the orientation to the base of the turbine, no matter what direction the turbine faces, base defined as the point of connection to the energy output) to the turbine's blades.
  • the FDD is superior to the turbine's blades. According to another embodiment, the FDD is inferior and superior to the turbine's blades.
  • the FDD is not connected to the body of the turbine. According to another embodiment, the FDD forms a ring around the shaft.
  • the turbine is in a liquid. It is now disclosed for the first time an FDD for a turbine, comprising: a. an intermediate partial outline foil shape, wherein the foil is adjacent to the turbine blades by a distance of less than 10% of the foil's outer diameter. b. a substantially vertical flange at the end of the foil shape on one side.
  • system further comprises c. a substantially vertical flange at the end of the foil shape on the second side.
  • FDD is functionally adjacent to a vertical axis turbine.
  • the FDD is functionally adjacent to a vertical axis turbine.
  • the intermediate shape is a "C" foil.
  • a vertical axis turbine comprising: a) proportional parameters of Db 1.96 meters, and Hb 1.5-3 meters within a 10% margin of their values. b) at least one functionally adjacent FDD in a vertical orientation.
  • the system further comprises additional parameters of the FDD according to cases in the following table, with a margin of error of 10% of the value of chord length, Din, or angle of attack, in any proportional size, or of the Hl or H2 parameters by a margin of 10% of the chord of the foil in any proportional size, for any one, two, three, four, or five of the parameters in the columns below:
  • a vertical axis turbine comprising: an inferior or superior FDD, with the proportion of a Din of 1.0-1.8 meters or greater in relation to a chord length of .4 to .9 meters, with an angle of attack of 5 degrees or greater.
  • a vertical axis turbine comprising an FDD, wherein fluid vortices as determined by fluid dynamic analysis and/or testing are not present from passage of fluid without blades in the internal diameter of the FDD from the bottom to the top of the FDD.
