- Abstract
When the -Re_ transition model is used to calculate the aerodynamic performance of the wind turbine airfoils, the SIMPLE algorithm is usually applied to solve the equation of speed and pressure for airfoil surface. Consequently the precision of the results by using SIMPLE algorithm is comparatively low. Therefore, For the newly wind turbine airfoil named CQU-DTU-LN118, COUPLED algorithm is selected to solve the equation of speed and pressure for airfoil fluid surface. The results of SIMPLE algorithm, COUPLED algorithm and wind tunnel experiments are studied comparably on the condition of Reynolds number of 2.1ž106 and the angle of attack from -8øto 15ø. Compared with the aerodynamic characteristics (such as pressure distribution, lift coefficients, drag coefficients and among others), it is found that the calculated data for COUPLED algorithm are the same as wind tunnel test. But the results calculated by SIMPLE algorithm are far away from experiment data when the airfoil is in the state of stall. The study validated the accuracy and applicability for the COUPLED algorithm used to simulate the wind turbine airfoils.
