Wide-range reference temperature-and-density based equations for the thermal conductivity of ethene and propene are given. These equations are based upon a body of critically assessed data, acquired partially using the transient hot wire method. The ethene correlation is valid from 110 to 680 K and up to 200 MPa with a maximum uncertainty of 5%. The propene correlation from 180 to 625 K at pressures up to 50 MPa, with an uncertainty of 5%....

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 reference equations for the thermal conductivity of n-heptane are expressed based on experimental data that has been critically assessed for consistency and for agreement with theory. A large part of the data was collected by the transient hot wire method. The theoretically expected enhancement in the critical region agrees with the data collected and can be well represented by theoretically based equations containing just one adjustable parameter. The ...

New representative equations for the thermal conductivity of toluene are expressed based on a body of experimental data collected mainly by the transient hot wire method. The data has been critically assessed for consistency and agreement with theory wherever possible. Due to the difficulties of the substance, data in the critical region is scarce. The data that was collected agreed with the theoretical enhancement expected in that region and can ...

An accurate representation of the thermal conductivity of methane and tetrafluoromethane in the limit of zero density valid for the temperature range 120–1000 K with a highest uncertainty of 4%. Also included is a temperature range of 280–750 K with a highest uncertainty of 5% for methane and tetrafluoromethane respectively. These theoretically based correlations are compared to bodies of data, collected mainly from the transient hot ...
