On prediction of the thermal conductivity of liquids

Abstract

Based on the Predvoditelev-Vargaftik formula, which relates uniquely thermal conductivity with density, a method is developed to predict the thermal conductivity of organic liquids, their mixtures, as well as petroleum products over a wide range of state parameters. The method employs a three-constant equation of state of a cellular model. The method is distinguished by the small amount of initial information required and an acceptable prediction accuracy.
