Close-contact melting (CCM) is a phenomenon that takes place when the phase change material (PCM) is not constrained where a thin layer of melted PCM forms between the heated surface and solid PCM and expedites the melting process. In this study, two validation studies are performed using the combination of the enthalpy-porosity method with modified melting temperature ranges and the volume of fluid method. First, a single layered RT42 enclosure is numerically studied and next, RT42 and RT31 are stacked on top of each other with a separator to investigate the effects of simultaneous CCM at different melting points. The results indicate that by modifying the melting temperature range of PCM the melting front depicts a steady behavior. In the double layered case, the CCM is evident for both layers and the melting time is found to be 30% lower compared with the single layered case because of increased CCM area and lower melting temperature of RT31.
