To study the dynamics of droplet splashing when super-cooled large droplets (SLD) impinge on solid surfaces, a code is developed for the quasi-steady simulation of two-dimensional SLD impingement in a Eulerian framework. The governing equations of the droplet phase, which incorporate two classical splashing models, the LEWICE splashing model and the FENSAP splashing model, are solved for the simulation of droplet-wall interaction. The mass and velocities given in the splashing models are incorporated in the solutions of the governing equations by modifying the source terms and then the splashing dynamics can be investigated. It is found that the distribution of the liquid water content (LWC) around the airfoil surface is changed due to splashing. Some commonalities and differences are investigated during the calculation and analysis of the two splashing models and this may be helpful in studying SLD impingement.
