ABSTRACT
The thermal conductivity of liquid dimethyl ether (DME) was measured from (233 to 373) K at pressures ranging from (0.6 to 30) MPa by the transient hot-wire technique with two anodized tantalum hot wires. The experimental data were correlated as a function of pressure and temperature. The average absolute deviation of experimental data from those calculated by the equation was 0.46 %, and the maximum absolute deviation was 1.6 %. The uncertainty of the thermal conductivity was ( 2.0 % with a coverage factor of k ) 2.
