The mechanical and thermal properties of structural steel were examined at ambient and high temperature to evaluate the predictive models of current design codes. Tensile coupon tests were performed to evaluate the mechanical properties. Thermal elongation was determined using a high-temperature extensometer, while the thermal conductivity and specific heat capacity were determined using the transient plane source technique. Specifically, the slab method was used. The determined mechanical properties were used ...
The fatty acid stearic acid has been widely studied for its use in thermal energy storage applications as a phase change material (PCM). Stearic acid shows promise for this application because of its high volumetric storage density and its favorable thermal properties; however, two properties of stearic acid limit its use as a PCM: its low thermal conductivity and its propensity to leak liquid during the phase change process. This ...
Thermoelectric materials are currently being researched as a source of energy in order to reduce carbon dioxide emissions. The efficiency of these materials depends on their Seebeck coefficient, electrical resistivity, and thermal conductivity, as well as the absolute temperature. Cobalt oxides (Ca3Co4O9+delta) have been researched extensively as potential thermoelectric materials because of their high Seebeck coefficient and low electrical resistivity and thermal conductivity. Systems have been studied ...
The development of higher power chips in the electronics industry has led to the requirement of high performance thermal interface materials (TIMs) due to the increased heat output by these chips. Desirable features of a high performance TIM include that the material be highly thermally conductive, and that it should have a relatively low viscosity. Companies can spend long periods of time trying to find the amount of filler content ...
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....
