摘要	The Spalart-Allmaras turbulence model is used to investigate the aerodynamic performance of a wind turbine airfoil DU00-W-212. Numerical simulation results show different performances both rough and smooth airfoil when Reynolds number changes in a small region. The effect of Reynolds number on aerodynamic performance of rough airfoil are studied. The curve of lift-drag coefficients reveals that the roughness is an important influencing factor upon the lift coefficient at attack angle of approximately 10°. Lift coefficient will descend and drag coefficient will ascend because of the rough leading edge at a small attack angle. However, the drag coefficient of a smooth airfoil is higher than that of the rough airfoil when the airfoil has gone into stall conditions. The region of the attack angle with the highest lift coefficient has to be avoided in the design proposal, thus improving the capability of the blade adapted to the harsh dust storm.
