Critical Review of Industrial Techniques for Thermal-Conductivity Measurements of Thermal Insulation Materials

The ability of leading thermal conductivity measurement techniques to be applied to the thermal measurement of thermally insulated materials was investigated. Researchers required that the equipment be able to operate between temperatures of 250 and 800°C. The equipment studied included the Transient Plane Source, the laser flash technique, the guarded heat flow meter, the transient hot wire instrument, and the guarded hot plate apparatus. Variables considered by the investigators included price, ...

Study on Comparison of Thermal Conductivities of Thermal Insulations Using Different Measurement Methods in Wide Range of Temperature

This article focuses on creating a standard reference material and method for measuring the thermal conductivity of thermal insulation materials at a set temperature. The specific focus is in the temperature range above 100°C, where there are differences in values obtained using different techniques. The author performs a review on the influences of the guarded hot plate, cyclic heat and transient hot wire. The author developed three apparatuses that measure ...


Thermal conductivity of porous materials

The effects of solid phase thermal conductivity, pore thermal conductivity, and pore volume fraction on the measured effective thermal conductivity of porous ceramics with pore volume fractions of 4 to 95% were investigated. The experimental results were then compared with pre-existing numerical models. It was found that the Maxwell-Eucken relation for closed porosity and the Landauer relation for open porosity were able to closely predict the effective thermal conductivity for tin oxide, ...

Thermal conductivity enhancement of nanostructure-based colloidal suspensions utilized as phase change materials for thermal energy storage: A review

The authors have presented a literature review on computational and experimental studies on the thermal conductivity of nanostructure enhanced phase change materials (nePCMs). It was found that a wide range of nanostructures have been investigated, from carbon nanostructures and carbon nanotubes to metal and metal oxide nanoparticles. The carbon nanostructures and nanotubes were found to generally enhance the thermal conductivity of the PCMs by a greater amount than metal or ...
