SIMULATION ANALYSIS OF AERODYNAMIC PERFORMANCE OF WIND TURBINE WITH VORTEX GENERATOR
摘要
Abstract
With the increase of blade length and unit capacity of wind turbine，and the proposal of blade lightweight design requirements，the use of large thickness airfoils has become the trend of blade design. In order to improve the aerodynamic performance of wind turbine with large thickness airfoils，it is an effective method to install vortex generators (VG) on the blade surface. In this paper，the simulation model of a certain type of wind turbine is established，and the simulation results obtained by CFD simulation analysis method are compared with the calculation results of wind turbine simulation software GH-Braded. Then the aerodynamic performance of the wind turbine before and after installing VG on blades is simulated and analyzed，and the shaft power of the wind wheel with and without the VG is compared under the typical working conditions before blade pitch. The research results show that the CFD simulation results are basically consistent with the GH-Braded calculation results， which veriifes the accuracy of the CFD simulation analysis method. When the wind speed and the wind wheel speed are high，the installation of the VG can increase the shaft power of the wind wheel by 1.94%，which proves that the installation of the VG can effectively improve the aerodynamic performance of the wind turbine， thereby improving the power generation efficiency of the wind turbine，which can be promoted in practical engineering applications.关键词
