A significant change in aerodynamic characteristics can occur by ice accretion on the surface of wind, turbine blade due to low temperature in cold climate. In particular, it will result in the loss in electricity production through a negative influence on lift and drag. In this study, the impact of ice accretions on the aerodynamic characteristics of wind, turbine blade sections is examined by computational methods. It is shown that the thickness of ice accretion increase and the lift-to-drag ratio decrease from the root to the tip.
