Abstract
|
Wind energy is one of the renewable energy , protect the environment and reduce conventional pollution, heavy minerals energy, to achieve sustainable socio-economic development is of strategic importance . Wind turbines convert wind energy into electrical energy , the wind turbine is its core equipment , key components of the wind turbine rotor blades . Therefore, the composition of a wind turbine blade airfoil most directly affect the performance of the wind turbine . In this thesis, a method to increase the flap Wind Turbine wheel airfoil and blade design by Fluent software analysis tools as this design method . The thesis consists of the following four parts : the basic theory of the wind turbine , the basic theory and method of the simulation of the flow field , the blade airfoil two-dimensional analysis , as well as single leaves three - dimensional flow field analysis . The basic theory of the wind turbine section describes the characteristic coefficient of the geometric parameters of the blade airfoil and aerodynamic characteristics of the airfoil aerodynamic performance , and Wind Turbine the wind wheel aerodynamic design of wind turbine blades . The simulation of the flow field of basic theories and methods section gives the basic equations of computational fluid dynamics , turbulence models , mesh and control equations discrete . The the blade airfoil two-dimensional analysis and the single blade three-dimensional flow field analysis section gives the specific method of calculation , the interception of a part of the process of image analysis , and based on the results given , flaps for airfoil and blade design feasible sex .
