【 摘 要 】

References(33)Cited-By(9)A coaxial cylindrical cell was constructed for measuring thermal conductivities of nine pure fluids (argon, nitrogen, oxygen, helium, carbon dioxide, methane, ethane, ethylene and propane) at temperatures ranging from 25 to 76°C under pressures up to 17.5 MPa. Thermal conductivities of two binary mixtures (argon-nitrogen and methane-ethylene) were also measured at 30.6, 50.6 and 76.6 °C under pressures up to 9.8 MPa. The apparatus was calibrated with eight kinds of gases. The Stiel-Thodos and Crooks-Daubert correlations were applied to predict the effect of pressure on the thermal conductivity of pure fluids. They were also extended to the mixtures by use of the van der Waals one-fluid model. Fairly good agreement was obtained with the experimental data as well as those from the literature except in the vicinity of the critical region.
