This study investigates the properties of a material to be used as an energy storage medium that can use energy stored from the summer months, and then release it during the winter. The proposed material uses a graphite foam, with ZnO coatings with a flower like morphology, to house a sugar alcohol phase change material (PCM). The thermal conductivity of the material was measured using a transient plane source (TPS) ...
Hydrate bearing sediments, found in permafrost, have great potential as a future energy source. Therefore, the thermal properties need to be determined to design drilling and gas extraction processes. The thermal conductivity was measured through a transient plane source (TPS) method. The thermal conductivity values show weak negative dependence on temperature. The effective thermal conductivity of hydrate-bearing sediment is strongly dependent on the water-saturation of the sand, the hydrates tend ...
The purpose of this study was to produce high porosity silica thermal insulators through gelation-freezing. The thermal conductivities of the insulators in relation to porosity and microstructure were measured by a thermal constant analyzer based on the transient plane source (TPS) method. The thermal conductivities of the S1 and S10 samples remained fairly constant despite temperature changes, and were mainly affected by solid and gas conduction....
Cadmium sulfide (CdS) nanoparticles were dispersed in a polystyrene (PS) matrix to synthesize semiconducting optical nanocomposites for industrial applications. In this paper, many characteristics of the PS-CdS thick films were studied including thermal conductivity using the transient plane source (TPS) method. Results showed that the thermally conductive CdS nanoparticles enhanced the thermal conductivity of the nanocomposites....
In this study, ultralow density silica aerogels were synthesized and their thermal conductivities were tested to determine how supercritical drying affected the samples. A thermal analyzer measured the thermal conductivity of the silica aerogels using the transient plane source (TPS) method which determined that the thermal conductivity of silica aerogels increased with temperature....
