    摘要： A family of dual-winglet rotor blades are designed to dissipate the low energy flow in the wake of a turbine rotor. In some embodiments a dual-winglet having a first winglet transitioning from the lift surface of a rotor blade and a second winglet transitioning from the pressure surface of the rotor blade creates two distinct streams in the wake of the rotor. In one embodiment the first winglet curving away from the lift surface turns the lift force toward the center of the rotor plane while a second, smaller, winglet curving away from the pressure surface of the rotor blade turns the lift force away from the center of the rotor plane. In other embodiments winglets create a virtual shroud that expands the wake to dissipate the low-energy flow in the turbine wake. In another embodiment a dual winglet combines the aforementioned mixing effect with the wake expansion effect.

    摘要： A fluid turbine comprises a turbine shroud, an ejector shroud, and a means for extracting energy from a fluid stream. The means for extracting energy is located in the annulus between the turbine shroud and the ejector shroud. High-energy fluid can flow through the turbine shroud to bypass the means for extracting energy. Energy is extracted from the fluid passing through the means to form a low-energy fluid stream. The high-energy fluid and the low-energy fluid can then be mixed. The turbine shroud and/or the ejector shroud has mixing lobes to increase the mixing of the two fluid streams.

    摘要： A semi-annular delta-airfoil is designed in conjunction with a fluid turbine rotor blade to provide increased rotor-tip speed, increased coefficient of power, reduced wind shear, reduced noise and increased self-yaw. A dual-winglet rotor blade in combination with a semi-annular delta-airfoil increases the above mentioned benefits by increasing the rotor-blade tip surface-area that is in contact with the area of increased fluid velocity over the semi-annular airfoil. Winglets on the semi-annular delta-airfoil provide self-yaw characteristics.
