Analysis of the Influence of Airfoil's Camber on the Performance Based on FLUENT

Airfoil's Camber has significant impact on its performance.Based on the standard k-e model which is widely used in engineering,the airfoils of different cambers are simulated.The numerical results show that both lift and drag force increase as the airfoil's camber increases.However,the increasing extent of lift coefficient decreases gradually.Best lift-to-drag ratio increases first,then the trend is decreasing.As the airfoil's camber increases,the minimum pressure of airfoil suction surface decreases,but the pressure is not below the fluid's vaporization-pressure.
