Effect of Time-Step Duration and Other Parameters on Ice Accretion

This work addresses the ice prediction cases studies for the 1st AIAA Ice Prediction Workshop generated using a mix of commercial and in-house tools. All predictions are compared with those by LEWICE. Results from both 2D NACA 23012 airfoil cases and 3D NACA 0012 swept wing cases have been included. It is observed that the computational tools have a much better correlation with experimental data for rime icing conditions. For glaze icing conditions, the ice horns are not accurately predicted. The impact of parameters such as surface temperature, heat transfer coefficient, and time-step for flow and droplet field re-computation is explored.
