In this study, the effective thermal conductivity of compacted granular beds is investigated. Thermal conductivity was measured using the transient plane source technique. Granular beds of varying particle sizes were analyzed using various sensor sizes. Results found the effective thermal conductivity to increase with increasing granule size. Smaller sensor sizes were also found to give a larger effective thermal conductivity....
This article looks at GMZ deposits as a candidate for buffer material of high-level radioactive wastes (HLW) in china. A thermal analyzer was used to measure thermal conductivity of compacted GMZ001 bentonite using the transient plane source technique. Results found that for samples having the same weight percentage of dry and wet density, thermal conductivity increased as the water content increased....
Thermal conductivity of 47 pairs of granitic rock specimens were measured using the Transient Plane Source (TPS) method. Crystalline rocks are being considered for the construction high-level radioactive waste (HLW) disposal systems. Dry and wet samples, the effect of water saturation, and the influence of temperature were all factors investigated in this study....
The present study investigates the experimental characterization of cementitious materials combined with four different carbon nanofillers; multi walled carbon nanotubes (MWCNTs), carbon nanofibers (CNFs), carbon black (CB) and graphene nanoplatelets (GNPs). Measurements of thermal conductivity and thermal diffusivity were carried out using the Transient Plane Source (TPS) technique. MWCNTs were found to influence thermal conductivity when they were aligned, compared to randomly distributed. GNP paste exhibited the highest thermal conductivity....
This study investigated new sol-gel methods in the fabrication of Al₂O₃ - SiO₂ composite aerogels. Compared to conventional methods, the Al₂O₃ - SiO₂ composite aerogels were prepared and mixed together. Thermal conductivity of the composite aerogels was measured by an instrument, using a transient plane heat source method....
