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....
The development of hydrogen storage materials for use in light-duty vehicles is investigated in this paper, which is still a ways off until commercial use. High-pressure metal hydrides (HPMH) are specifically studied here, at varying temperatures. The transient plane source (TPS) technique is used to measure the thermal conductivity and specific heat of the prepared hydride materials. Porosity and density are also important physical factors to consider when dealing with ...
