    摘要: Example embodiments described herein relate an integral and/or multi-piece airfoil and a shrouded fluid turbine having the same. The airfoil can have a generally circumferential body extending circumferentially about a central axis, and can be referred to herein as a “ringed airfoil.” The airfoil can have a front portion defining a leading edge of the airfoil and a rear portion defining a trailing edge of the air foil. A cross-sectional thickness of the front portion can be non-uniform and vary along a mean camber line of the airfoil from the leading edge to a transition area. A cross-sectional thickness of the rear portion can be uniform and constant along the mean camber line of the airfoil from the transition area to the trailing edge of the airfoil.

    摘要: A shrouded wind turbine comprises a shroud disposed about an impeller. The impeller surrounds a nacelle body which is shaped to enhance smooth flow of wind through the impeller. Some embodiments include an inlet and an outlet in the nacelle body, allowing airflow through an interior cavity. Other nacelle bodies may be tapered, flared, include mixing lobes around a trailing edge, or may have other shapes that enhance fluid flow. Some nacelle bodies include an annular groove that promotes flow attachment. Maintaining airflow attachment to the nacelle body within the turbine increases the energy generation capacity of the wind turbine.

    摘要: A golf ball having an indicia produced by ink jet printing is disclosed. An ink composition containing a coloring agent and a resin is dispensed on a transfer medium, using an ink jet printer, to form an indicia. The indicia is transferred from the transfer medium to the dimpled surface of a golf ball. In another form of the invention, an indicia is applied directly to a golf ball, without a transfer medium. In this method, an indicia receiving layer is applied on at least a portion of the golf ball surface, then the indicia is printed directly on the indicia receiving layer using an ink jet printer. The indicia on the golf ball has an impact resistance suitable for use in competitive play.
