THE THERMAL-CONDUCTIVITY OF DENSE FLUIDS AND THEIR MIXTURES USING THE EFFECTIVE DIAMETER REVISED ENSKOG THEORY

A method for calculating the thermal conductivity of dense fluids and their mixtures is described. This method relies on the results of the revised Enskog theory for hard-sphere fluid mixtures, and the use of the temperature and density dependent diameters given by Mansoori and Canfield, and Rasaiah and Stell. In addition, a correction in order to take into account the internal degrees of freedom contribution was introduced. A comparison with the conformal solution model, and with accurate experimental data was made. A very good agreement was found. © 1990.
