尾缘加厚翼型的三维旋转特性研究
Study on 3D rotation characteristics of trailing edge enlarged airfoils
摘要
Abstract
In this paper,Computational Fluid Dynamics (CFD) method was employed to predict the lift and drag coefficients of airfoils at different radii of MEXICO (Model EXperiments In Controlled cOnditions) experimental wind turbine,the computational results were compared with experimental results to validate the prediction accuracy of CFD,the results show that CFD can predict the lift and drag coefficients of airfoils under rotating conditions accurately.Then,CFD method was used to predict the aerodynamic characteristics of a rotor which is newly designed with trailing edge enlarged airfoil and the same chord length along the radial direction,so the characteristics of trailing edge enlarged airfoil under rotating conditions can be obtained which show that the lift coefficients of trailing edge enlarged airfoil is 10 percent larger than that of respectively original airfoil below an angle of attack of 15 degrees.What's more,the roughness sensitivity of trailing edge enlarged airfoil is better than that of respectively original airfoil under rotating conditions.At last,with the increase of radius,the lift coefficients of trailing edge enlarged and original airfoils both increase but stall occurs ahead,the increment of lift coefficients of trailing edge enlarged airfoil is larger than that of respectively original airfoil under rotating conditions.关键词
