An inter-comparison of a steady-state and transient methods for measuring the thermal conductivity of thin specimens of masonry materials

The aim of this study was to determine whether steady-state methods were better at measuring thermal conductivities of oven-fired clay masonry materials than transient methods, and vice versa. The Transient Plane Source (TPS) Method was tested, and when the results were compared with the other transient methods, there was an agreement of better than +/-3%. Overall, the thermal conductivity values recorded for the transient methods were higher than when the ...

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 ...


Intercomparison of Measurements of the Thermophysical Properties of Polymethyl Methacrylate

The authors used a variety of techniques to determine the thermal properties of polymethyl methacrylate (PMMA), including thermal conductivity, thermal diffusivity, specific heat and density. The measurements are performed in the temperature range from -70°C to 80°C. The results from the different techniques used to characterize the PMMA (GHP, GHF, TPS, THS) are all compared to see whether they agree with one another....
