Experimental investigation on thermal and rheological properties of n-octadecane with dispersed TiO2 nanoparticles 

The thermal and rheological properties of n-octadecane, a phase change material, with dispersed TiO2 nanoparticles were investigated at varying temperatures. The properties were investigated in both the solid and liquid phases, with varying mass fractions of TiO2 nanoparticles. The thermal conductivity was found to be enhanced in all of the composite samples when compared to the thermal conductivity of pure n-octadecane, and the maximum enhancement occurred at 3 wt. % TiO2 in ...

Temperature Dependence of Thermophysical Properties of Disodium Hydrogenphosphate Dodecahydrate

Disodium hydrogenphosphate dodecahydrate was investigated for its thermophysical properties and the effects that temperature had on these properties. The goal of this work was to determine if this material was a suitable phase change material for use in supercooled thermal energy storage. It was found that this hydrate could efficiently exchange energy between itself and heat sources, it could reduce heat loss from energy storage systems, and it could store ...

Investigation on Thermal Conductivity, Viscosity and Stability of Nanofluids

The thermal conductivity, viscosity, and stability of nanofluids were evaluated to determine how varying experimental conditions can affect these properties. It was determined that increasing the concentration, temperature, and time spent sonicating the nanofluids can increase the thermal conductivity, while the addition of alcohol caused a decrease in thermal conductivity. Furthermore, it was found that the shape of the particles has an effect on the measured thermal conductivity. It was ...

Online monitoring of wax deposition in sub-sea pipelines

The authors have performed a study to determine if heat pulse wax monitoring is capable of measuring the wax thickness build-up in an oil pipeline. A numerical model was developed to simulate the heat pulse equipment and to predict the wax thickness based on the experimental results....

Combined effect of physical properties and convective heat transfer coefficient of nanofluids on their cooling efficiency

The authors have developed a model for the estimation of how a nanofluid will work as a coolant without having to perform a number of experiments. The nanofluids used in the study were four water based metallic oxides. These nanofluids were compared to water in terms of thermal conductivity to determine if they would be a good coolant. The model that was developed involved the calculation of the highest wall ...
