Abstract
A new correlation with four parameters for the temperature dependent thermal conductivity of saturated liquids has been proposed in this paper. This correlation can be used to investigate the correlation between the temperature \(T\) and the thermal conductivity \(\lambda \) of various types of considered saturated liquids. By comparing this correlation with other previously published correlations, it is found that the accuracy of the new correlation is higher than others. In addition, the temperature range where it covers is wider. The lowest temperature that we studied is the triple point temperature, and the highest temperature is about 0.98 times the critical temperature. For the 50 saturated liquids studied here, the new correlation leads to an averaged absolute deviations (AAD) of less than 0.5% for 49 liquids and less than 1% for all the liquids.
