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 effects of particle size/shape, base fluid, and volumetric concentration on the thermal conductivity of nanofluids has been studied. It was found that decreasing the particle size leads to an increased thermal conductivity, and that using water as a base fluid led to the greatest enhancement of thermal conductivity. The effects of gravity, Brownian motion, and thermophoresis on particle motion were also investigated and it was found that gravity ...
Three techniques were compared for the determination of thermal conductivity in poly-alpha-olefin (PAO)-based nanofluids. The three methods that were used were the transient hot wire, transient plane source, and laser flash techniques. The effects of temperature, nanoparticle concentration, and shape on the thermal conductivity were also examined, and these effects were compared to those predicted by a previously determined model. It was found that the transient hot wire technique ...
The authors have dispersed mesoporous silica (MPSiO2) nanoparticles in water and determined the thermal conductivity for each of the resulting nanofluids. It was determined that the thermal conductivity of the nanofluid was greater than that of water, so these nanofluids have potential for use in heat exchanger applications....
