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 ...
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....
