Abstract

Abstract: A study on blunt trailing edge wind turbine airfoil TR-4000-2000 is lunched to investigate the changing trend of flow filed structure and aerodynamic characteristics when the synthetic jet existing on suction surface. Keeping the constant velocity of jet, unsteady numerical simulation of airfoil flow field in different attack corner is performed by the mean of Computational Fluid Dynamics software FLUENT, and the influence caused by jet on aerodynamic characteristics and the pressure fluctuation on airfoil surface are analyzed, based on this, the best jet parameters are determined threw numerical simulation in different jet velocity and frequency. The analytic results show that the lift and drag characteristic of the airfoil constant changes because of interaction between the synthetic Jet and the trailing edge vortex, the synthetic jet on suction surface has significant effect on lift promotion and drag reduction, and the result is particularly obvious at attack angle of 15, where lift coefficient increases 40%, and drag coefficient decreases 15%. Besides, the best jet effect occurs when the dimensionless jet velocity and the dimensionless frequency are both 1.

Key words: blunt trailing edge airfoil, lift and drag characteristic, numerical simulation, pressure fluctuation
