Abstract�� The arnold engineering development center (AEDC) icing scaling method was introduced and validated through numerical simulation. By icing modeling software, icing numerical simulations were performed for NACA0012 airfoil and its 1/2 and 1/3 scale models, cylinder and its 1/2 scale model. Flow field, droplets impingement and ice accretion computations were all included in the simulations. Scaling icing conditions were chosen according to AEDC method. The results show that the reference and scaling icing process have a wonderful similarity. It can be concluded that the AEDC method is effective and icing numerical simulation can be used in icing similarity research.
Keywords�� icing scaling   theory of similarity   numerical simulation
