The effect of ice accretion on the wake of an airfoil section is studied using Large Eddy Simulations (LES) for the flow computations and Lagrangian Particle Tracking (LPT) to track water droplets impacting on the surface. The flow around a clean airfoil is computed together with two cases with the same amount of accreted ice, but different smoothness of the ice layer. The computations revealed that ice accretion influences less the average velocity field and more the velocity fluctuations.
