In recent years , wind power as a clean energy , the world has been widespread concern and development ; research carried out for the whole wind turbine technology , more and more attention . Wind Turbine aerodynamic performance analysis , forecast and leaf design has also become a hot research scholars today . In this paper, a numerical method , reverse engineering and other means in different condition leaves the aerodynamic performance of wind turbine wind power characteristics of the wind turbine . The main research contents are as follows : First, the physical three-dimensional modeling of wind turbine blades based on reverse engineering technology . Application of three-dimensional digitized laser scanning technology to collect leaves a solid surface point cloud ; pretreated the data point clouds , NURBS surface fitting method refactoring blades entity model , and processing of the experimental wind turbine blades , and then for wind Turbine aerodynamic performance of wind tunnel tests provide the necessary geometric model . Secondly, the manufacturing of the wind turbine model , for the wind tunnel experiment , the measured growth curve of the wind turbine changes over time , the deceleration curve and power curve , and other data , then calculate the wind power, wind power coefficient characteristic curve , and analyze. Also on the real machine experiments under natural wind field test . Finally, the numerical simulation of the aerodynamic performance of the two wind turbine models . Determine the numerical calculation , the geometric model of the computational domain , the wind wheel meshing , finite volume method , based on the pressure correction method using in k-ωSST turbulence model for the whole three-dimensional steady turbulent , access to the wind turbine blades the flow characteristics of the surface of the pressure, velocity , flow lines , etc. . Many different stream wind velocity conditions axis wind turbine power curve calculated and compared with the wind tunnel test data to draw better consistency of results of numerical calculation and the experimental values ??.
