摘要： This invention relates to a method and a wind turbine blade, wherein one or more airflow modifying devices are attached to a wind turbine blade having a base aerodynamic profile. The base aerodynamic profile is configured to substantially carry the structural loading of this modified wind turbine blade. The airflow modifying device is manufactured via 3D-printing and/or via 3D-machining and optionally coated or laminated before attachment. Once attached, the airflow modifying device may further be coated or laminated before working the outer surfaces into their finished shape.

摘要： A method is provided for reducing the noise emission of a wind turbine rotor blade. The rotor blade has a leading edge, a trailing edge, a suction side, a pressure side and an attachment part at least partially on the pressure side. A pressure-side transition is present between the pressure side and the attachment part. The pressure-side transition is leveled by applying a leveling compound.

摘要： A device for attaching to a surface of a wind turbine blade is described. The device comprises a plurality of sections to be arranged end-to-end along a portion of the blade. Each section of the device comprises: a baseplate for bonding to the surface of the blade; a first panel extending from the baseplate; first and second end walls extending respectively along transverse edges of the baseplate and the first panel; a first tab extending from the first end wall; and a second tab extending from the second end wall, the second tab being transversely offset from the first tab. The tabs are arranged such that when the sections are positioned end-to-end with a first end wall of a first section adjacent to a second end wall of a second section, the first tab of the first section overlaps the second end wall of the second section, whilst the second tab of the second section overlaps the first end wall of the first section. An associated method of mounting the device is also described, which avoids the risk of compromising adhesive and/or sealant during the mounting process.

摘要： The invention provides a method for computational fluid dynamics and apparatuses making enable an efficient implementation and use of an enhanced jet-effect, either the Coanda-jet-effect, the hydrophobic jet-effect, or the waving-jet-effect, triggered by specifically shaped corpuses and tunnels. The method is based on the approaches of the kinetic theory of matter, thermodynamics, and continuum mechanics, providing generalized equations of fluid motion. The method is applicable for slow-flowing as well as fast-flowing real compressible-extendable fluids and enables optimal design of convergent-divergent nozzles, providing for the most efficient jet-thrust. The method can be applied to airfoil shape optimization for bodies flying separately and in a multi-stage cascaded sequence. The method enables apparatuses for electricity harvesting from the fluid heat-energy, providing a positive net-efficiency. The method enables efficient water-harvesting from air. The method enables generators for practical-expedient power harvesting using constructive interference of waves due to the waving jet-effect.

The profile (1-4) includes a camber line (21, 25) and a chord (18) between a leading edge (10) and a trailing edge (11) of the profile (1-4). The profile (1-4) has a relative profile thickness of more than 45%. At least one vortex generator (50, 50′, 50″, 50′″) is disposed, in the region of the profile (1-4), on the suction side (7) of the rotor blade (5). The profile (1-4) is provided with a blunt trailing edge. And, The thickness of the trailing edge is between 15% and 70% of the chord length.

摘要： A method for installing an add-on component onto a tip of a wind turbine blade, the associated blade, and the component, are provided. The add-on component has a span-wise end and a separated trailing edge, and is slidable onto the blade tip. Strips of a double-sided adhesive tape are attached onto either or both pressure and suction side surfaces of the blade adjacent the blade tip, or onto interior surfaces of the add-on component, the tape strips having a release liner on an opposite exposed side thereof. An extension tail is configured with the release liner that extends beyond the span-wise end of the add-on component when the add-on component is placed and held at a desired position on the blade. The add-on component is slid onto and maintained in position on the blade tip and, starting from the tape strip furthest from the separated trailing edge, extension tails of the respective tape strips are sequentially peeled through the separated trailing edge and away from the add-on component.
