The application of thermal conductivity measurements to the Kuqa River profile, China, and implications for petrochemical generation

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 ...

Thermal performances of asphalt mixtures using recycled tyre rubber as mineral filler

Recycled tyre rubber was used to replace varying fractions of limestone as filler in asphalt in order to determine the effect that the added rubber would have on the thermal and physical properties of the asphalt. The properties of interest were the penetration, soft point, and ductility of the asphalt binder, as well as the moisture sensitivity, thermal conductivity, thermal diffusivity, and volumetric thermal capacity of the asphalt mixtures. It ...

Effect of hexagonal boron nitride on high-performance polyether ether ketone composites

Polyether Ether Ketone (PEEK)/hexagonal boron nitride (h-BN) nanocomposites were formed by a planetary ball milling process and hot compression molding in order to determine the effect of the addition of h-BN on the properties of PEEK. In particular, the tensile strength, friction and wear behaviors, morphology, hardness, thermomechanical properties, and thermal conductivity of the nanocomposite were examined. Hexagonal boron nitride was added in filler concentrations of up to 5 wt. %. ...

Closed-cell carbon foams from diphenolic acid-based polybenzoxazine

Carbon foams were prepared from diphenolic acid-based benzoxazine foams by pyrolysis under nitrogen atmosphere. The method used in this article produced foams containing a large fraction of closed cells which is uncommon for carbon foams. The foams studied were found to possess similar mechanical properties common to other carbon foams; however, the presence of the high fraction of closed cells led to the lowest observed thermal conductivity ever reported for ...

Comparative Studies on Thermal Performance of Conic Cut Twist Tape Inserts with SiO2 and TiO2 Nanofluids

In an effort to enhance heat transfer in the laminar flow regime of a heating duct, TiO2 and SiO2 nanoparticles were added to water to create nanofluids with a higher thermal conductivity than that of the water alone. Twist-tape was also used to enhance heat transfer within the duct. The thermal conductivities of the nanofluids were measured using the Transient Plane Source  instrument. It was found that the use of ...
