Category: Transient Hot Wire
Abstract: 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 just one adjustable parameter. These correlations are applicable from the triple point of each fluid to 700 K, and whatever pressure that relates to the maximum density limit for the equation of state used to provide density. The highest uncertainties for each o-, m-, p-xylene, and ethylbenzene are respectively, 4%, 6%, 3.6% and 2.8%. The uncertainties are much higher in the critical regions for each substance.
