This study is to determine the thermal properties of a paraffin/red brick composite to determine its viability as a form-stable phase change material. Extended graphite was also added to the composite to improve its thermal conductivity. The thermal conductivity for this material was measured using a transient plane source (TPS) method. By adding the paraffin, the thermal conductivity of the composite increase, also by adding extended graphite the thermal ...
Nitrate materials play an important role in the development of latent thermal energy storage (LTES) systems. This paper examined the thermo-physical properties of sodium nitrate, potassium nitrate and their mixtures with expanded graphite (EG) additives for their applications in solar energy storage. The transient hot-wire method measured the apparent thermal conductivities of the nitrates and nitrates/EG mixtures. Results showed that nitrates/EG mixture PCMs with the highest concentrations of ...
Paraffin is an excellent phase change material (PCM) for latent heat storage, but it does not efficiently use stored energy because of its low thermal conductivity. In this study, nickel and copper foams were added to paraffin to enhance heat transfer. A Thermal Constants Analyzer measured the thermal conductivity of the paraffin composites using the transient plane source (TPS) method. The addition of copper foam enhanced the thermal conductivity of ...
Nanoparticle-enhanced phase change materials (NePCMs) are nanofluids that can be used for thermal energy storage when they undergo solid-liquid phase transitions. In this study, a Thermal Constants Analyzer (TPS) measured the thermal conductivity of eicosane-based NePCM samples using the transient plane source (TPS) method. Results showed that thermal conductivity of the solid composites increased with temperature, and eicosane-CuO samples that solidified in an ice-water bath had the lowest thermal conductivities, ...
Epoxy resin/silicon carbide (Ep/SiC) composites were prepared by the casting method and subsequently characterized for their mechanical and thermal properties. It was determined that an increasing mass fraction of SiC in the epoxy resin resulted in increasing thermal conductivity of the composites. Using 50 wt.% SiC resulted in a thermal conductivity of 0.7152 W/mK, which is three times that of pure epoxy resin. Mechanical properties peaked with 10 wt.% SiC. ...
