Optimal Design of Wind Turbine Airfoils Aimed for Aerodynamic Performance of Wind Wheel
摘要
Abstract
A design method for optimizing the aerodynamic performance of wind turbine airfoils is pre-sented. The calculation is optimized on the existing wind turbine airfoil through changing the outline of the range from the position of its maximum thickness to its trailing edge. The flow field and aerodynam-ic characteristic of airfoil are obtained by using the Navier-Stokes (N-S) equations, then the method of two-dimensional linear interpolation is used for multi-objective optimization, which is tried to increase the tangential force while reducing the normal force of wind turbine simultaneously. Taking the DU93-W210 airfoil as an example,aiming at the contradiction of the wind turbine airfoil aerodynamic character-istic of itself, several programs are proposed and improved according to the actual needs. The results show that the design method proposed can get good effect under different performance requirement.关键词
