The thermal transport properties of Ti1.1CrMn powder were determined. This metal hydride shows promise for use in hydrogen storage applications due to its excellent cold-start properties. The thermal conductivity, thermal diffusivity, and specific heat of oxidized and activated powder samples of this metal hydride were determined using the transient plane source technique in a high pressure vessel. It was found that the effective thermal conductivity of the samples showed ...
The thermal transport properties of nanofluids containing single-walled carbon nanotubes (SWCNTs) in ethylene glycol and (poly)-alpha olefins (PAO) were investigated. It was found that the addition of SWCNTs enhanced the thermal conductivity of each of the two base fluids, with this enhancement increasing as the loading of SWCNTs increased. The authors were able to create an accurate predictive model of the thermal conductivity for these nanofluids by characterizing the ...
The density related properties (specific gravity, density, apparent porosity), and thermal transport properties were determined for diorite and granite rocks taken from the Shewa-Shahbaz Garhi volcanic complex, Pakistan. All measurements were made at varying temperatures from 253-333 K to determine the effect of temperature on the properties. It was found that all of the properties investigated depended on the chemical composition of the rock samples. For a given sample, the ...
The thermal properties of synthetic gas hydrate-bearing sediment samples were determined by the transient plane source method. The samples were made up of sand, water, gas, and methane hydrates, and these samples were supercooled to minimize the effects of the heat of fusion of methane hydrate on the thermal conductivity measurements. The thermal conductivity was found to increase with increasing methane hydrate saturation for saturations from 0-0.3. Thermophysical models were ...
Thermal properties of methane hydrate-bearing sediment samples taken from the Nankai Trough, Japan were investigated using the transient plane source method. It was determined that the thermal conductivity of these sediment samples decreased with increasing porosity, but increased with increasing methane hydrate saturation. The thermal diffusivity of the samples increased slightly with increasing porosity, but was almost independent of methane hydrate saturation. It was also found that the specific heat ...
