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 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%....
Using a bare and a coated hot-wire apparatus, new data has been collected to determine the thermal conductivity of liquid water along the saturation line. This reference material data was collected with extremely high accuracy so the correlation presented is within revised a previous correlation that is endorsed by IUPAC, making it standard reference data....
The transient line source technique was used to take thermal conductivity measurements over the entire liquid range of toluene at 1atm. Unlike any other liquid (with the exception of water) the thermal conductivity was not completely a linear function of temperature. Instead, there was an anomaly pre-freezing where the thermal conductivity dropped from what was expected. This paper attributes this behavior to ...
This article examined the effects of using the traditional vertical orientation method versus the single-sided horizontal method for transient thermal conductivity measurements of water, glycol, and methanol. It aimed to understand whether the single-sided horizontal method was effective at suppressing the onset of natural convection during the tests. From the analyses, it was seen that the proposed single-sided horizontal method can effectively suppress the onset of natural convection during the ...
