The objective of this study was to evaluate the transient plane source method for thermal conductivity and diffusivity of food and agricultural materials. An instrument was used to measure thermal conductivity of liquid and solid samples. Thermal conductivity and diffusivity values determined by the TPS method were in close agreement with reported literature values....
This research looked to investigate the thermal conductivity and heating performance of asphalt mixtures containing steel slag and steel wool fibers (SWF). An instrument was used with the transient plane source method, to evaluate the effect of SWF and steel slag on the thermal conductivity of asphalt. Results showed that as the content of SWF increased to 6%, the asphalt mixtures had a higher thermal conductivity. At 8% SWF content, the uneven ...
Thermal conductivity of alumina and kaolin clay were investigated as a function of the water content at different stages of drying compared to linear shrinkage. Thermal conductivities of the samples were measured using the transient plane source methods. Samples were encapsulated in a polyvinyl film to ensure a constant temperature in the sample while drying. Results found thermal conductivity varied at the beginning as values increased, then decreased significantly at ...
This study investigated the relationship between hygrothermal properties and bulk density of compressed earthen bricks. Thermal conductivity of compressed earthen samples was measured using a thermal apparatus with transient plane source method. Compressed earthen material with lower bulk density was found to have a lower thermal conductivity than higher bulk density materials since low bulk density samples have more pores filled with air....
Bentonite buffer is a key element in a high-level radioactive waste (HLW) repository as it dissipates decay heat from the waste to the surrounding rock. This article looked at Kyeongju bentonite as a candidate buffer material and investigated the dependence of thermal conductivity on various experimental conditions. A thermal analyzer instrument was used to measure thermal conductivity using the transient plane source method. Thermal conductivity was found to increase with ...
