In the present paper, a numerical and experimental study is implemented to analyze the melting behavior of a Latent Heat Thermal Energy Storage System (LHTES) in a horizontal cylinder with using paraffin 27 as the Phase Change Materials (PCM). By varying the internal diameter and wall temperature of the horizontal cylinder, the liquid fraction and mean heat transfer coefficient are adopted to evaluate the effect of Stefan number (Ste) and Grashof number (Gr) on the phase change process of PCM. The results indicate that both the effect of wall temperature and internal diameter on the melting pr...
