  • The purpose of this paper is to study the effect of the moist air over an airfoil. The influence of moist air on the airfoil aerodynamic characteristics is very important for the optimization of offshore wind turbine airfoil and improving the efficiency of wind turbine. Firstly, the lift and drag of airfoil is calculated by using the component transport model. Then, the condensation of water vapor in the moist air is considered, and the condensation volume source is defined by the user defined function in fluent. The preliminary study on the aerodynamic performance of the moist air flow over airfoil shows that the lift and drag coefficient will change with the humidity. The condensation mass flux near the leading edge of the airfoil is the largest, and condensation mass flux of the airfoil increases with the increase of humidity. The condensation mass flux is higher at high temperature.
