Embodiment Construction

[0050] The present invention will be further described below in conjunction with specific examples.

[0051] The method for determining the installation position and size of the wind turbine blade vortex generator provided in this embodiment is as follows:

[0052] 1) Establishment of 3D model of initial smooth blade calculation watershed

[0053] According to the aerodynamic dimension parameters of a large-scale wind turbine blade actually operating in a wind farm, the initial smooth three-dimensional model of the wind turbine blade is established by using CATIA software, and the external calculation of the initial smooth wind turbine blade is determined according to the actual operating conditions of the large-scale wind turbine 3D model of the watershed.

[0054] 2) Mesh division of the 3D model of the initial smooth blade calculation watershed

[0055] The CFD professional pre-processing software ICEM is used to divide the 3D model of the initial smooth blade calculation...

Abstract

The invention discloses a method for determining the installation position and size of a vortex generator of a wind power blade, comprising the steps of: 1) establishment of a three-dimensional model of an initial smooth blade calculation watershed; 2) grid division of the three-dimensional model of an initial smooth blade calculation watershed; 3) Numerical simulation calculation considering the transition; 4) determination of the installation position of the vortex generator; 5) determination of the size of the vortex generator; 6) evaluation of the effect of the vortex generator; 7) optimization process. The invention can greatly improve the control effect of the vortex generator on the flow separation of the boundary layer, and overcome the problem that the particle deposits in the wind field cannot meet the requirements of the wind turbine manufacturer for the project period due to the long test period and the inability to better determine the size of the vortex generator. The lack of demand and the need for supporting production of blades provide a theoretical basis for more reasonably determining the installation position and size of the vortex generator for wind power blades.

Description

technical field [0001] The invention relates to the technical field of renewable new energy wind power blades, in particular to a method for determining the installation position and size of a vortex generator of a wind power blade. Background technique [0002] The trend of large-scale wind power blades is becoming more and more obvious. With the increase of blade size, the phenomenon of laminar flow separation on the surface of the blades of wind turbines is more and more likely to occur during actual operation. Therefore, controlling the laminar flow separation on the surface of large wind power blades to It is particularly important to realize blade increase and drag reduction. [0003] Manufacturers of wind turbines improve the flow conditions on the blade surface by installing vortex generators on the blade surface, that is, the vortex generators are used to suppress the separation of the laminar boundary layer on the blade surface, so as to achieve the effect of the v...
