The viscosity and thermal conductivity of normal hydrogen in the limit of zero density

With a basis upon the semi-classical kinetic theory of polyatomic gases and critically examined data, a new representation of the viscosity and thermal conductivity coefficients of normal hydrogen is created in the limit of zero density as a function of temperature. Measurements are made with the transient hot wire method, among others, and are taken between 20 and 2200 Kelvin. The highest uncertainties are 2%, ...

Thermal Conductivity of Molten Lead-Free Solders

This paper investigates the thermal capacity of multiple varieties of lead-free molten solder for application in electrical equipment. An accurate understanding of these properties would lead to a better controlled soldering process. Measurements are taken by a transient hot wire that was originally designed to be used on pure molten metals, but an improved finite-element code analyzed the data (this is called ...

Physical Properties of 7-Methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (mTBD)

7-Methyl-1,5,7-triazabicyclo[4,40]dec-5-ene (mTBD) is an important industrial chemical that is commonly used as a catalyst. Prior to the research conducted by Baird et al, the only available data on this chemical pertained to its density and a single vapor pressure value that is provided on chemical safety data sheets. This paper presents the first reliable, publicly available data on the thermodynamic and transport properties of mTBD. These values ...

Reference Correlations for the Thermal Conductivity of 13 Inorganic Molten Salts

Employing many techniques, including that of the transient hot wire, experimental data relating to the thermal conductivity of 13 inorganic molten salts have been gathered and critically examined with the purpose of building a reference correlation. The data in this paper was gathered at a 95% confidence level....

Correlation of the Thermal Conductivity of Normal and Parahydrogen from the Triple Point to 1000 K and up to 100 MPa

Thermal conductivity measurements of hydrogen and parahydrogen were taken over a temperature range from their triple point to 1000 Kelvin. A new theoretically based correlation was then adopted that agreed well with existing data and explained the case of the dilute-gas thermal conductivity. The analysis displayed that in the critical region, the enhanced thermal conductivity can be well represented with an equation containing ...
