Extended Abstract

The value of the thermal conductivity λm of organic liquid mixtures is required in several engineering problems, but experimental data exist for only a small portion of the enormous variety of the possible mixtures, and the measurements generally are carried out at only one value of temperature. A general correlation [1,2], proposed for pure organic and inorganic liquids, in the reduced temperature range 0.3 to 0.8 and at atmospheric pressure or along the saturation line, was generalized in the form [3]:
$${{\lambda }_{m}} = \left[ {{{A}_{1}}x_{1}^{2} + {{A}_{2}}x_{2}^{2} + n\sqrt {{{{A}_{1}}{{A}_{2}}}} {{x}_{1}}{{x}_{2}}} \right]\frac{{{{{\left[ {1 - {{T}_{{rm}}}} \right]}}^{{0.38}}}}}{{T_{{rm}}^{{ \frac{1}{6} }}}}$$
(1)
in order to predict the thermal conductivity λm of the organic liquid binary mixtures. In equation [1] A1 and A2 are factors characteristic of the mixture’s components, x1 and x2 their respective molar concentrations, n a pure number independent of x1 and x2 ranging from 1.0 to 2.0, and Trm the “critical” temperature of the mixture, obtained by a linear mole — fraction average. The mean and maximum deviation between predicted and experimental thermal conductivity data for 30 binary mixtures were 1.8% and 8.3% respectively.
