The authors are part of a European project known as DISTOR which seeks to investigate new systems for storage of thermal energy in phase change materials (PCMs). Reported in the article is a detailed model of heat transfer and fluid flow for the prediction of those values for promising PCMs. Some assumptions are made in order to prepare a simplified model. A machine is used to measure the thermal conductivity ...
Sebacic acid (SA) can be absorbed into the pores of expanded graphite (EG) to form a SA/EG composite phase change material (PCM). There is no chemical interaction between the SA and EG, they are merely integrated. The optimal amount of SA was found to be 85 wt.% of the total mixture. The 85 wt.% composite had a phase change temperature of ~ 128°C, with a latent heat of ~ 187 J/g. The thermal ...
The addition of graphene nanoplatelets (GNP) to a paraffin-based solvent, eicosane was performed at various wt.% and subsequently the synthesized GNP/eicosane composites were analyzed by a variety of machines. The characterization of the GNP/eicosane composites was performed by the TPS technique for the measurement of thermal conductivity from 10°C to 35°C. At a wt.% of 10 GNP filler the composite had a thermal conductivity four times that of unfilled ...
Microencapsulated phase change materials (MPCMs) are excellent materials for the storage of thermal energy, and through their dispersal into a carrier fluid, microencapsulated phase change slurries (MPCS) can be prepared. These slurries exhibit both excellent thermal energy storage and heat transfer properties. A series of MPCS were prepared for this research and subsequently tested for thermal conductivity and specific heat. Other methods of quantification include DSC, TGA, rheometry, and infrared ...
A series of fabrics containing different mass ratios of polyurethane binder to melamine-formaldehyde microcapsules were created and their thermal properties were investigated. A variety of thermal analysis methods including guarded hot plate and differential scanning calorimetry were employed to characterize the series of fabrics. The mass ratio of microcapsules to polyurethane binder had a significant effect on the thermal properties of the fabrics and the researchers pointed out a specific ...
