Using the transient plane source (TPS) technique, researchers measured the thermal conductivity, thermal diffusivity and specific heat capacity of an electrically insulating ceramic material prepared from kaolin and feldspar. The electroceramic was tested at multiple temperature points to see how it affected thermal conductivity. Thermal properties were strongly affected by temperature, and the ceramic material studied had the highest thermal conductivity and thermal diffusivity at the highest temperature tested. The ...
Carbon fiber and magnetite (Fe3O4)-doped epoxy memory shape polymers were prepared with 2.5% volume fraction of each dopant. These materials were doped in the hope of increasing the thermal performance of the polymers. Using the Thermal Constants Analyzer, thermal conductivity, thermal diffusivity and specific heat of the doped polymers were measured. Specifically, the researchers were looking into changes exhibited near the transition temperature of the shape memory polymer of ...
Using the transient plane source (TPS) technique, the effect of addition of pine tree particles to styrene butadiene rubber is studied. Thermal conductivity, thermal diffusivity, specific heat capacity and density were all investigated. Varying amounts of the pine tree filler particles were added to the polymer matrix in order to form composites. Increasing amounts of the pine tree filler resulted in higher thermal conductivity and thermal diffusivity, with decreasing specific ...
Two series of nanofluids were prepared by the researchers, using water as the carrier fluid, and Al2O3 and TiO2 as the nanoparticles; up to 6% particle volume fraction was used. The thermal conductivity and thermal diffusivity of the nanofluids were measured using the transient plane source (TPS) technique, and dynamic viscosity was also measured. The amount of nanoparticle volume fraction affected the value of thermal conductivity, but the nanoparticle cluster ...
An investigation was undertaken to try to gain insight into altered thermal properties of the seafloor near Japan caused by the earthquake and subsequent tsunami that devastated Japan and caused the meltdown of the nuclear reactor in Fukushima in 2011. Core samples of rock were drilled by the JFAST project and these samples were analyzed using the transient plane source (TPS) technique to determine thermal conductivity, thermal diffusivity and volumetric heat ...
