Researchers have been developing techniques to predict inlight icing in order to determine aircraft behavior under different icing conditions. A key component of the techniques is the mesh generation strategy. Automated meshing facilitates numerical simulation of ice accretion on realistic aircraft configurations by deforming the surface and volume meshes in response to the evolving ice shape. The objective of this research is to validate an ice accretion strategy for wings, using a previously developed meshing strategy. The intent is to investigate the effect of varying numerical parameters, on the predicted ice shape. Using this framework, results are simulated for rime and glaze ice accretions on a rectangular planform wing with a constant GLC-305 airfoil section. The number of time steps is shown to have a significant effect on the ice shape, depending on the icing time and conditions. Decreasing the height smoothing parameters generally improves the ice shape accuracy.
