摘要：

The　binary　eutectic　mixtures　of　fatty　acid　esters　are　promising　phase　change　materials　for　energy　storage　application.　However,　the　low　thermal　conductivity　which　is　a　common　problem　for　organic　phase　change　materials　restricts　their　further　and　better　applications.　In　order　to　solve　the　problem,　a　novel　composite　phase　change　material　(CPCM)　was　prepared　in　this　research　by　using　methyl　palmitate-methyl　stearate　(MP-MS),　a　typical　binary　eutectic　mixture　of　fatty　acid　esters,　as　phase　change　material　and　expanded　graphite　(EG)　as　heat　transfer　enhancer.　The　heat　transfer　performance　of　MP-MS/EG　CPCM　was　numerical　simulated　by　finite　element　analysis　software　ABAQUS.　Numerical　simulation　results　revealed　that　EG　could　notably　enhance　the　heat　transfer　performance　of　MP-MS　eutectic　mixture.　The　heat　transfer　rate　and　phase　change　reaction　rate　of　MP-MS/EG　CPCM　were　14　times　and　3　times　that　of　MP-MS　eutectic　mixture,　respectively.　©　2020　Trans　Tech　Publications　Ltd,　Switzerland.
