Abstract: A wind turbine blade is provided. The wind turbine blade includes a root region, a tip region, and a body extending from the root region to the tip region. The tip region includes a first winglet and a second winglet that extend arcuately away from one another.

Abstract: A system includes a rotary isobaric pressure exchanger (IPX) having an oblique ramp disposed within a fluid inlet of an end cover at an oblique angle configured to direct a fluid toward an interior surface of a channel within a rotor to facilitate rotation of the rotor. In addition, the system may include one or vanes disposed within the fluid inlet to further direct the fluid toward the interior surface. Further, the system may include one or more passages extending from the fluid inlet toward a surface of the end cover that interfaces with the rotor, where the one or more passages utilize the fluid to apply additional force to the rotor to facilitate rotation.

Abstract: A wind turbine blade includes a root region. A first extension (LEX) is attached to the leading edge side of the root region while a trailing edge strake (TES) is attached to the trailing edge side of the root region. The LEX and TES each include an outer profile that becomes more pronounced relative to their respective locations in the root region as the root region of the wind turbine blade morphs from a substantially cylindrical shape to a substantially airfoil shape. The LEX provides both optimal angle of attack and lift generation in the root region, while the TES mitigates airflow separation and enhances airfoil lift in the root region.
