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%, ...
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 ...
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....
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 ...
Liquid toluene is a material used in industrial processes, and generally the thermal conductivity needs to be determined for efficient use. However, the thermal conductivity varies depending on high temperatures and other physical variables. The transient hot wire method has previously been used to obtain measurements of the thermal conductivity of toluene under multiple conditions to create reference data. This paper displays ...
