Thermophysical and structural properties of sintered ore particles (SOPs) were determined to expand upon the little documented information there is regarding the properties of these materials. In addition to this, a fractal model was also developed for the prediction of thermal conductivity in SOPs as a function of porosity. The experimental results revealed that the specific heat capacity increased with increasing temperature and that the thermal conductivity decreased with increasing ...
The authors outline a method of enhancing the thermal properties of a paraffin phase change material through the addition of herringbone-style graphite nanofibers (HGNFs). It was found that the solid-phase thermal conductivity increased exponentially with the presence of HGNFs; however, a significant increase in the liquid-phase thermal conductivity was not observed until the concentration of HGNFs in the composite PCM reached a point above the percolation threshold. The volumetric heat ...
The thermal conductivities of 6 rocks containing gypsum, as well as 6 rocks in which gypsum is absent were determined experimentally. The rock samples were taken from the Kuqa depression, in the north of the Tarim Basin, China. It was determined that gypsum-bearing rocks are thermal insulators, and this property when combined with other properties of gypsum-bearing rocks make them good cap rocks and also make them suitable for oil production and ...
The ability of asphalt as a solar collector is studied with the help of the transient plane source (TPS) technique. Tubes were embedded into the asphalt slab and were used to circulate water, which collected the heat from the asphalt slabs....
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 ...
