摘要： An airflow generation device of an embodiment has a main body and a voltage application unit. The main body has a base formed of an insulating material and provided with a first electrode and a second electrode. The voltage application unit generates an airflow by applying voltage between the first electrode and the second electrode. Here, the main body is formed to include a portion which gradually decreases in thickness from a center portion to an end portion. The idea is to avoid leading edge flow separation by generating a plasma locally.

摘要： A wind turbine includes a nacelle that houses a dynamo and a vane wheel coupled to an end of the dynamo. The nacelle is movably mounted to a post. The nacelle has a body forming a circumferentially extending curved slot that has a front portion forming a reducing section and a rear portion forming an expanding section. The vane wheel has a hub at a center thereof and including a plurality of blades radially extending therefrom. Each blade has an end forming a down wash. With the curved design of the nacelle body, the rising angle of airflow exiting the nacelle is improved and with the down wash, the occurrence of tip vortex is suppressed, whereby the utilization efficiency of wind energy in the wind generation operations is improved.

摘要： An advantageous new design of a wind turbine blade and rotor is obtained by providing one, two or more parallel rows of sub-boundary layer vortex generators, whereby a blade is obtained, which is resistant to stall and provides for a high maximum lift coefficient CL,max of the blades and a slender blade design, a low socalled radius specific solidity of the rotor. The very high lift coefficient CL can reduce the necessary blade area and loads or/and increase the length of the blade and maintain the original loads with higher production. The row or rows of sub-boundary layer vortex generators are in a preferred embodiment of the invention provided in combination with Gurney Flaps generating a very high lift coefficient CL with a relative gentle stall at very high angle of attack.

摘要： A blade (10) for a rotor of a wind turbine (2) has a substantially horizontal rotor shaft, the rotor comprising a hub (8), from which the blade (10) extends substantially in a radial direction when mounted to the hub (8). The blade comprises a profiled contour including a leading edge (18) and a trailing edge (20) as well as a pressure side and a suction side, the profiled contour when being impacted by an incident airflow generating a lift. The profiled contour is divided into a root region (30) with a substantially circular profile closest to the hub, an airfoil region (34) with a lift generating profile furthest away from the hub, and a transition region (32) between the root region (30) and the airfoil region (34). The profile of the transition region (32) gradually changes in the radial direction from the circular profile of the root region to the lift generating profile of the airfoil region. The suction side comprises at least a first zone (40, 42), which extends substantially in the direction of the incident airflow, and which is positioned in a zone of a cross-flow. The first zone (40, 42) comprises a first barrier generating means (x06) adapted to generating a barrier of airflow, which extends essentially in the direction of the incident airflow, the barrier of airflow being of sufficient strength and length so as to effectively reduce the cross-flow.
