Popis: The aim of this paper is to present the Italian icing computational environment code, I 2 CE, developed by CIRA, and discuss its evaluation for ice accretion on single and multielement airfoils. The aerodynamic module of the code is based on a potential panel method, whereas the thermodynamic module is based on the classic Messinger model. Different ways to solve the time-dependent ice accretion problem have been taken into account. A comparison between theoretical calculations using multi-time-step, single-time-step, or predictor-corrector procedures and experimental data has been carried out. The effect of the flowfield viscosity on droplet trajectories and the influence of different approaches for the convective heat exchange coefficient calculation have been considered. The influence on the impingement of the actual droplet size distribution has been taken into account and a comparison with a standard median volumetric diameter calculation is presented
