TL;DR: In this article, the viscosity and thermal conductivity for nitrogen, oxygen, argon, and air were derived using an approach adopted from previous work on the equation of state for air.
Abstract: New formulations for the viscosity and thermal conductivity for nitrogen, oxygen, argon, and air are given. Air is treated as a pseudo-pure fluid using an approach adopted from previous research on the equation of state for air. The equations are valid over all liquid and vapor states, and a simplified cross-over equation was used to model the behavior of the critical enhancement for thermal conductivity. The extrapolation behavior of the equations for nitrogen and argon well below their triple points was monitored so that both could be used as reference equations for extended corresponding states applications. The uncertainties of calculated values from the equations are generally within 2% for nitrogen and argon and within 5% for oxygen and air, except in the critical region where the uncertainties are higher. Comparisons with the available experimental data are given.

TL;DR: The Tait equation as discussed by the authors is a modification of the original equation of Tait, published 100 years ago, to fit his results on the compressibility of fresh water and seawater at different pressures.
Abstract: The “Tait equation,” which is now widely used to fit liquid density data over wide pressure ranges, is a modification of the original equation of Tait, published 100 years ago, to fit his results on the compressibility of fresh water and seawater at different pressures. The range of applicability of these different equations is discussed and it is concluded that their simplicity and accuracy in reproducing high pressure density data for dense gases, liquids, solids, and liquid mixtures will ensure their continued use.

TL;DR: In this paper, the effects of the morphologies (size and shape) of the added solid phase on the enhancement of the thermal conductivity of the nanoparticle suspension are reported for the first time.
Abstract: Nanosized SiC suspensions were prepared, and their thermal conductivities were measured using a transient hot-wire method. The experimental results showed that the thermal conductivities of the studied suspensions were increased as expected, and the enhancement was proportional to the volume fraction of the solid phase, but the increasing ratio of the thermal conductivity was not significantly related to the base fluid. The effects of the morphologies (size and shape) of the added solid phase on the enhancement of the thermal conductivity of the nanoparticle suspension are reported for the first time.

TL;DR: In this article, an experimental measurement program was performed to determine thermophysical properties of aluminum-based foam metals, and the effective thermal conductivity ke and permeability K were investigated in detail.
Abstract: An experimental measurement program was performed to determine thermophysical properties of aluminum-based foam metals. The effective thermal conductivity ke and permeability K were investigated in detail. Experimental facilities were fabricated, and the measurement procedures and methodologies were evaluated. One-dimensional heat conduction was considered to determine ke . The results indicate that ke increases as the porosity e decreases. However, no noticeable changes in ke were detected from variations of the cell size of the foam metal at a fixed porosity e. The permeability K is substantially affected by both e and the cell size. An empirical correlation for the friction factor f is proposed based on the concepts of K and inertial effect.

TL;DR: In this paper, the enhancement of the thermal conductivity of water in the presence of carbon-multiwall nanotubes (C-MWNTs) was investigated, and a transient hot-wire instrument was built for this purpose, and operated with a standard uncertainty better than 2.
Abstract: The enhancement of the thermal conductivity of water in the presence of carbon-multiwall nanotubes (C-MWNT) was investigated. Sodium dodecyl sulfate (SDS) was employed as the dispersant, and a 0.6 vol% suspension of C-MWNT in water was used in all measurements. The thermal conductivity was measured with a transient hot-wire instrument built for this purpose, and operated with a standard uncertainty better than 2 The maximum thermal conductivity enhancement obtained was 38 %. In an attempt to explain the experimental observations, a number of micro-structural investigations have been carried out and those results are presented here along with the analysis.
