The present disclosure relates to a heat dissipation system, a wind generating set, and a heat dissipation supporting platform. The heat dissipation system includes: a supporting platform, the supporting platform including a body portion, the body portion including an inlet, an outlet, a flow channel communicating the inlet with the outlet, and a mounting position for mounting a functional device, the inlet, the outlet and the flow channel together form a medium circulation passage; and a heat exchange apparatus which communicates with the medium circulation passage and delivers the cooling medium into the medium circulation passage, the cooling medium flowing through the inlet and the flow channel and flowing out from the outlet to exchange heat with the functional device.

A wind turbine blade (10) is described having a serrated trailing edge (20). Splitter plates (106) are provided on the blade, to reduce operational noise. Each splitter plate (106) is arranged to extend at least partly into a space in between adjacent serrations. The splitter plates can be formed integrally with the serrations, or attached to existing serrations as a retrofit solution. The serrations with the splitter plates can be provided as a trailing edge panel (108) for attachment to the trailing edge of an existing wind turbine blade.

An airfoil body may include a plurality of tubercles along a leading edge of the airfoil body and a plurality of crenulations along a trailing edge of the airfoil body, wherein at least one of a position, a size, and a shape of the plurality of tubercles and the plurality of crenulations varies in a non-periodic fashion. The non-periodic fashion may be according to a Fibonacci function and may mimic the configuration of a pectoral fin of a humpback whale. The tubercles and crenulations may be defined with respect to a pivot point. The spanwise profile, including the max chord trailing edge curvature, may closely follow divine spirals and related Fibonacci proportions. The spanwise chord thickness may vary in a nonlinear pattern. Related methods are also described.

The present disclosure is directed to a method of manufacturing a rotor blade for a wind turbine. The method includes providing a blade mold of the rotor blade. Another step includes placing an outer skin layer in the blade mold. The method also includes placing one or more structural inserts in the blade mold atop the outer skin layer as a function of a load of the rotor blade. Further, each of the structural inserts includes a plurality of cells arranged in a predetermined pattern. Further, the cells have varying cell sizes. The method also includes placing an inner skin layer atop the one or more structural inserts and securing the outer skin layer, the one or more structural inserts, and the inner skin layer together to form the rotor blade.

A turbine blade for a wind turbine, the turbine blade has a blowing and suction provision in form of a plurality of arrays of blowing and suction holes defined on a curved suction surface of the turbine blade. An apparatus for turbine blade testing includes the turbine blade. The apparatus also includes a wind tunnel, a blowing source, and a suction source. The wind tunnel includes a wind channel having first and second end plates for mounting the turbine blade. A method of testing air flow in a turbine blade involves changing holes used for blowing and suction and determining a momentum coefficient for those various holes; and varying angle of attack with measurement of lift/drag ratio.

A wind-speed accelerating wind turbine has the wind turbine installed in the nacelle, the nacelle has a front nacelle member having a cross-section area formed so as to linearly or curvilinearly contract from a wind inlet to an installed position of the wind turbine and has a rear nacelle member having the contracted cross-section area formed so as to linearly or curvilinearly expand or maintain the same cross-section area from the installed position of the wind turbine to a wind outlet, and a wind dispersion part or a wind dispersion shape is provided at the wind outlet of the rear nacelle member.
