This study used macroscopic equations to determine fluid dynamics and heat transport properties in metallic slip-reaction (SR)-foams for their application in gas turbines. The numerical results were validated by an experimental method that analyzed the physical and mechanical properties of the SR-foams. An apparatus measured the effective thermal conductivity of the foam samples using the transient plane source (TPS) method. Results showed that the foams had low thermal conductivities ...
Aerogels are nano-porous materials with impressive thermal insulation properties. This study uses a new theoretical model to predict the effective thermal conductivity of aerogels based on gas and solid conduction, as well as thermal radiation. A thermal constant analyzer measured the influence of gas pressure, atmosphere, and temperature on the thermal conductivity of nano-porous materials using the transient plane source (TPS) method. Results showed that the experimental thermal conductivity values ...
Asphalt solar collector (ASC) is a conductive asphalt concrete and an eco-friendly method to de-ice roadways. This study examined if the addition of conductive fillers and various mixing parameters could improve the thermal conductivity and energy efficiency of ASC. A thermal conductivity system measured the thermal conductivity of the concrete samples using the transient plane source (TPS) method. Results showed that thermal conductivity was mostly improved by higher asphalt temperatures, ...
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....
Seasonal thermal storage based on phase change materials (PCMs) require a thermally conductive host because they typically have low thermal conductivities. In this study, tannin-based composite carbon foams were prepared using thermally conductive exfoliated graphite (EG) fillers and pMDI additives. A thermal analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results showed that the EG-carbon foams and the EG/pDMI-carbon foams showed significantly ...
