PREDICTION OF THE THERMAL CONDUCTIVITY OF FLUID MIXTURES.
Abstract
A corresponding states method, introduced previously, to predict transport coefficients of a pure fluid or mixture over a wide range of experimental conditions is expanded. The thermal conductivity coefficient is discussed in detail. It is shown that this coefficient can be predicted given only values for a reference fluid and thermodynamic data. Comparisons between calculated results and data are satisfactory. The effect of internal degrees of freedom is discussed. The behavior of the thermal conductivity coefficient at the critical point (for a pure fluid) or the plait point (for a mixture) is also mentioned briefly.
