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 ...
Thermal conductivity and thermal diffusivity of two poly(methyl methacrylates) were measured using multiple methods; temperature wave analysis, laser flash, transient plane source, transient line-source probe, and heat flux meter. The main reasoning behind this study was to compare results between methods, to ensure repeatability among methods. Good agreement was shown among thermal conductivity and thermal diffusivity results between instruments, however the transient plane source method repeatedly yielded 6% higher results ...
