The enthalpy method based on this model clarifies the sedimentation of a solid PCM and the appearance of close contact melting which is very significant. Furthermore, the analyzed result elucidates qualitatively the melting process of a solid PCM which was obtained by the experiment.6 pagesPDFenUniversity of PretoriaPhase change materialUnconstrained melting analysisPCMSedimentation of a solid PCMPresentation
