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 ...
When thermal conductivity and diffusivity are measured with a thermal constants analyzer, sensors of different designs are being used. Sensors are primarily made of nickel foil, arranged in a double spiral, sandwiched between two thin sheets of insulating material. For experiments between 30 and 450 K, the ...
