O-xylene, m-xylene, p-xylene, and ethylbenzene are all given new representative reference equations for their thermal conductivities based upon experimental data that has been critically assessed for consistency and agreement with theory. This data was collected in part due to the transient hot wire method. The theoretically expected enhancements in the critical regions of all four agree with the data collected and can be well represented by theoretically based equations containing ...
New representative equations based on critically assessed experimental data obtained through the thermal hot wire technique, among others, are put forth for the thermal conductance of sulfur hexafluoride (SF6). These correlations are applicable from the triple point to temperatures up to 1000 K, and pressures up to 150 MPa with overall uncertainties less than 4 percent....
A new design was presented of a portable transient hot wire apparatus for measuring the thermal conductivity of solids. The design features a two-wire sensor with silicon layers, compact printed electronic board and a high-tech software suite that utilizes the Finite Elements Method to model heat flow. This methodology is 120x's faster than any previous approach and can reduce the number of ...
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 ...
