Aerogels have a wide range of properties that make them effective thermal insulators. However, these properties are lost when the materials absorb too much water. The goal of this experiment was to determine how temperature and humidity affect the insulative properties of silica nano-porous aerogels. A thermal constants analyzer measured the thermal conductivity of moist silica nano-porous materials using the transient plane source (TPS) method. Results showed that the thermal ...
In this paper, cost efficient RVC foams were fabricated from household cleaning pad waste (CPW) and sucrose. A thermal analyzer measured the thermal conductivity of the RVC foams using the transient plane source (TPS) method. Results showed that the thermal conductivity of the CPW foams were significantly lower than Ultramet’s RVC foams which are highly insulative. This study proved that it is possible to reproduce low-cost carbon foams from ...
Gas hydrates have potential to be used as future energy sources, so it is important to understand their thermal properties. This paper aims to examine the effective thermal conductivity of synthetic porous methane hydrate samples. A Thermal Constants Analyser measured the thermal conductivity of the methane hydrate samples using the single-sided transient plane source (TPS) method. Results showed an inverse relationship between porosity and thermal conductivity. Unfortunately, mechanical pressure can ...
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 ...
Porous materials have widespread industrial applications. In this study, mullite materials with porosities between 72-86 vol% were fabricated and a thermal analyzer (TPS) measured their thermal conductivity using the transient plane source (TPS) technique. Results showed that as the porosity of the mullite materials decreased, thermal conductivity increased....
