Study on Roughess Sensitivity of Genreal Profiles for Wind Turbine Airfoils
摘要
Abstract
Based on the boundary layer theory,a separation model of the wind turbine airfoils was presented.The transformation of pressure and velocity field on the airfoil surface were discussed.Compared with the traditional inverse design method,one direct and integral method for airfoil design was presented.Using the function equation of general wind turbine airfoil profile,an integrated mathematical model was presented.The roughess sensitivity of the general wind airfoil was calculated.The relation between the separation position,different Re number and aerodynamic performance were investigated for the general wind airfoils.The results provide enough theoretical support for the design of good performance and low roughess sensitivity.The design method and theory for wind turbine airfoils are developed.关键词
