Abstract: In order to understand the flow and heat transfer characteristics of phase change slurry, the floating and melting process of an ice particle in water is numerically studied. The free-floating process of an ice particle under various forces is numerically modelled, and the melting process of solid particle is described by enthalpy-porous method. The model is implemented to study the floating and non-uniform melting process of an ice particle at different temperature variations and internal supercooling degrees. The morphological change of ice particle and the thermo-fluidic characteristics during floating and melting process are obtained. It is found that the internal supercooling degree of ice particle delays the melting of ice particle.

Key words: ice particle; supercooling; free-floating; non-uniform melting
