This article aimed to analyze the abilities of self-assembled microcapsules containing calcium carbonate shells and paraffin-based binary cores to act as thermal energy storages. The thermal properties of the microcapsules, such as thermal conductivity and phase change properties, were obtained using the transient plane source (TPS) method and analyzed using an instrument. It was found that the thermal conductivity of the microcapsules was enhanced due to their highly thermally conductive ...
This study focused on the heat transfer enhancement mechanism of micro oscillating heat pipes (MOHP) using self-rewetting fluids (SRWF). SRWFs are believed to improve the thermal performance of heat transfer devices. Thermal conductivity measurements were taken with a thermal analyzer, using the transient plane source method at room temperature. Results found the thermal conductivity of SRWF to be slightly lower than that of water, and MOHP using SRWF exhibited much ...
The authors have prepared a shape-stabilized composite phase change material (ss-CPCM) using paraffin encapsulated in SiO2. SiO2 was chosen because of its low cost, such that the resultant ss-CPCM would be a feasible option for use at the commercial or industrial scale. The composite was examined using FTIR and XRD and it was confirmed that it had excellent chemical compatibility and stability. The thermal storage capability and thermal conductivity results ...
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 ...
