Abstract

Experimental results for the thermal conductivities of liquid CO2 are reported. The thermal conductivities were measured by a transient short-hot-wire method. Experimental temperatures ranged from 273.8 to 294.5 K, and pressures from 4.0 to 15.0 MPa. The uncertainty of the reported thermal conductivity data was estimated to be within ±3.0%. The experimental data were compared with calculated values from the REFPROP 8.0.
