New independent representations of the viscosity and
thermal conductivity of ethane in the limit of zero density. For viscosity, the correlation is over the temperature range of 200 to 1000 K, with the highest uncertainty being 2.5% . The correlation for thermal conductivity covers from 225 to 725 K with a highest uncertainty of 3%....

In the past twenty years, the behavior of the apparent
thermal conductance of two or three phase systems comprised of solid particles with nanometer dimensions suspended in fluids, dubbed nanofluids, has been greatly contested in literature. After the study of the seven simplest nanofluids, Cu, CuO, Al
2O
3, and TiO
2 suspended in water and ethylene glycol, ...

Multiple studies claiming the usefulness of
nanofluids for the enhancement of heat transport have been proven ill-founded. Although they have significantly raised thermal conductivities, there is an inerrant increase in viscosity when adding nanoparticles to a liquid. This paper explores areas of research that analyze nanofluid properties that could potiential indicate future applications. A promising direction is using particles that can change ...

The use of the transient hot wire method has previously displayed that the
thermal conductivity of fluids can be significantly increased by introducing nano-particles. The paper discusses the known methods for predicting the thermal conductivity and finding correlations amongst data. When preforming initial simulations employing the Finite Element Method (FEM), this paper shows that there is still substantial experimental progress to be ...

Seven distinct samples of nanofluids consisting of different concentrations of spherical graphitized carbon black in an ethylene glycol solution were analyzed to determine their thermal and rheological behavior. The
thermal conductivity measurements were made at 20°C and 30°C with a transient hot wire instrument made by Thermtest called THW-L2 and specifically designed to measure the thermal conductivity of liquids. This study was ...
