ABSTRACT

New experimental data on the thermal conductivity of methylcyclohexane and propylcyclohexane are reported that allow the developement of wide-range correlations. These new experimental data, covering a temperature range of 300 K to 600 K and a pressure range of 0.1 MPa to 60 MPa, are used to develop correlations for the thermal conductivity. The experimental data reported here have an uncertainty of less than 1 % for measurements removed from the critucal pount and for gas at low pressures (less than 1 MPa). Based on the uncertainty of and comparisons with the present data, the thermal conductivity correlations for methylcyclohexane and propylcyclohexane are estimated to have a relative uncertainty of about 4 % at a 95 % confidence level. The present data include a contribution due to thermal radiation that increases in proportion to temperature cubed up to estimated value from 2 % to 3 % near 600 K.
