摘要
The thermal conductivities of dimethyl sulfoxide + ethanol, dimethyl sulfoxide + water, and dimethyl sulfoxide + ethanol + water were reported. The measurements, covering a temperature range from (278.15 to 338.15) K were performed by a transient hot-wire technique over the whole concentration range at atmospheric pressure. The experimental data of thermal conductivity were correlated by the second-order Scheffe polynomial in terms of temperature and weight fraction. The average absolute deviation of those correlated values from the experimental data was 1.35 %. The uncertainty of thermal conductivity was +/- 2.0 % with a coverage factor of k = 2.
