%X For the aerofoil of small wind turbine working under the conditions of low-Reynolds, the aerodynamic performance of seagull aerofoil and NACA 4412 is contrastively analyzed while the Reynolds-Number is กข and by the Fluent. The numerical simulation comparison shows that, when the attack-angle range is 0กใ~20กใ, the life-coefficient of seagull aerofoil increased 24.97%กข46.02% and 48.54% than NACA 4412 respectively; when the attack angle is 4กใ, the lift-drag ratio of seagull aerofoil increased 40.44%กข43.14%บอ39.40% than NACA 4412 respectively. Under the condition of Reynolds-Number is , the normal working range of attack angle of seagull aerofoil increased 16.7% than NACA 4412 .Under the same simulation condition, the separation point of NACA4412 aerofoil is closer to the leading-edge than seagull aerofoil . The analysis shows that the unique distribution of the thickness and the camber of the seagull aerofoil is the main reason of the better aerodynamic characteristics under the Low-Reynolds.Keywords: Low-Reynolds; wind turbine; aerofoil; numerical simulation; aerodynamic characteristics
