The authors created a series of composite latent storage materials (CLSM) using expanded graphite (EG) and a two different metal nitrate phase change materials (K and Li, K and Na). The steady-state comparative method was used in order to measure thermal conductivities because it was deemed the best technique. Properties investigated that were related to the effective thermal conductivity were material temperature and microstructure and their effect on thermal conductivity....
Using the TPS method, the authors measured the thermal conductivity and thermal diffusivity of samples of Swedish wood. They also looked at the effect of density, porosity and anisotropy on the measured thermal properties. Both longitudinal and transverse measurements were taken at temperatures ranging from 20°C to 100°C and an increase in temperature resulted in a slight increase in thermal conductivity. The types of mechanisms that lead to heat conduction ...
A collection of AlSi7 foams (porosities 0.5 to 0.8) were analyzed using the TPS technique in order to determine thermal conductivity. Increased density was found to lead to increased thermal conductivity. The TPS technique was found to be sensitive to the in-homogeneities created from the foaming process; therefore the foaming process is an important factor in the determination of thermal conductivity of a given foam. The authors also combined several theoretical models ...
The authors of this article look to use shredded waste tires as a component of a cement composite in order to reuse the discarded material as well as improve the thermal properties of the composite. The TPS method was used in order to determine thermal conductivities of the dry components of the composite, and the auto-coherent homogenisation model was used to determine the thermal conductivity of the rubber/cement/air ...
