Abstract: The rate of solidification of phase change materials can affect the efficiency of latent heat storage systems. This paper proposes the use of CAD to model the solidification process of a phase change material around a vertical finned tube. The approach uses a digital camera to capture the time progression of the solidification phase front. The captured 2D images are then transformed to solid models using a CAD software package. This approach is currently restricted to solidification processes that are symmetrical about an axis of revolution. Future work will focus on more complex solidification processes.

Keywords: solid modelling; freezing; vertical finned tubes; phase change materials; CAD; solidification; latent heat storage.
