NUMERICAL SIMULATION OF DROPLET IMPINGING ICING PROCESS ON A LOW TEMPERATURE WALL WITH SMOOTHED PARTICLE HYDRODYNAMICS METHOD

ABSTRACT
Based on the basic principles and improved algorithms of the smoothed particle hydrodynamics method, a corresponding surface tension model and latent heat model are proposed for the heat exchange phase transition problem of droplets impinging on a low temperature wall surface. This research establishes a novel smoothed particle hydrodynamics model of the impinging wall of droplets accompanied by the phase transition process. This work also includes simulations cov¬ering the spreading flow and phase transition process of droplets under different impingement regimes. Moreover, the icing patterns of the droplet impingement spreading process are provided and a comparative analysis with related experi¬mental results. The improved smoothed particle hydrodynamics model is verified by experiments and its ability to solve droplet impingement icing problems.
