The Thermal Conductivity of Liquid Mixtures

Abstract

The thermal conductivity of a set of eight alkane/silicone oil mixtures has been determined as a function of composition using a guarded horizontal parallel-plate apparatus. The data obtained have been analyzed by comparison with available correlations for predicting the thermal conductivity of a mixture from those of its components. A suitable correlation has been selected after modifying its form. The effect of the sizes of the component molecules on the thermal conductivity of the mixtures has been demonstrated.

Thermal Conductivities of Liquid Hydrocarbons and Their Binary Mixtures

“…Although several calculation methods for thermal conductivities of liquids and their mixtures have been published by several investigators (Filippov, 1955;Jamieson and Hastings, 1969;Li, 1976; Losenicky, 1968), they are essentially empirical. Semitheoretical approaches based on the molecular model of Horrocks and McLaughlin (1960) have also been reported by Gaitonde et al (1978) and Saksena and Harminder (1974). However, they are not sufficient for extending the model to mixtures.…”
