Abstract: Ridge ice can severely deteriorate the airfoil’s aerodynamic performance.Numerical simulation was conducted to determine the effect of simulated upper-surface spanwise ice shapes such as ice-shape location,ice-shape size and Reynolds number on airfoil aerodynamics.The simulation results show that decreases of lift coefficient and stall angle of attack as well as increases of drag coefficient can be caused by ridge ice.Besides,the effect of ice-shape windward on aerodynamic coefficients is greater than downstream ice-shape.In particular,the upper surface critical ice-shape location tended to be in between the location of minimum pressure and the location of the most adverse pressure gradient.With the increment of ice-shape size,effect on airfoil aerodynamics also increases.However,change of airfoil aerodynamics under different Reynolds number is slight.
